Of all kinds winter sports Most often, the two most spectacular ones are singled out. This is hockey and biathlon. The USSR, and then Russia, have always been proud of their merits and achievements in these sports. Take, for example, Kharlamov in hockey or Tikhonov (four-time Olympic champion) in biathlon. Everything is clear with a hockey player’s equipment - skates, stick, helmet. With biathlon, everything is much more interesting and attractive, since in fact it is a double sport - skiing and shooting. Regarding equipment for movement, everything is also clear: the main thing is to guess the lubricant according to the weather, but with a biathlete’s weapon, which is a rifle, everything is not so simple. The participant will have to make a difficult choice regarding the brand, since the result of successful shooting depends on this. Therefore, experienced athletes carefully select weapons. What does a biathlon rifle look like? Her photos will be presented to the reader later in the article. In the meantime, let's do it small excursion into history and find out when and under what circumstances this type of sporting weapon appeared.
A little history
At the end of the Second World War, the most popular competitions were military patrols; in essence, this was the prototype of modern biathlon. The equipment at that time was ordinary army combat equipment, which also included a bayonet-knife. By the way, they were in service Soviet army during the war with Germany.
After much debate by the International Olympic Committee, the long-awaited debut performance of biathletes at the winter events took place in 1960. Olympic Games Oh. For Soviet athletes, the Izhevsk Machine-Building Plant produced the Biathlon-59 rifle in pilot production. The sight of a biathlon rifle at that time was diopter. It was also equipped with carrying straps and a special protective case. The weight of a biathlon rifle at that time was not strictly regulated.
Course for modernization and improvement
After the 1960 Winter Olympics, weapons designer Sherstyakov, using the Mosin rifle as a basis, produced a new weapon for biathlon. The resulting sample was produced in two versions and had names depending on the caliber: “Biathlon Bi-7.62” and “Biathlon Bi-6.5” (their cartridges had dimensions of 7.62 mm and 6.5 mm respectively).
The use of this particular weapon brought Soviet biathletes their first Olympic successes, in particular, Vladimir Melanin was able to win his first at the Winter Olympics in Innsbruck in 1964. gold medal in biathlon.
In the early seventies, the production of the new Biathlon Bi-4 rifle began, which was fired with rimfire cartridges. The model had significantly less weight. The next new product was released just a year after the release of the previous one and was called “Biathlon Bi-5”. The shooting was carried out with central firing cartridges of 5.6 mm caliber. It was with this rifle that the victorious golden march of four-time Olympic champion Alexander Tikhonov began.
Weapons of competitors
Not only in the Soviet Union they knew how to make weapons for biathlon. Foreign manufacturers should also be noted. The most famous companies are Anschutz and Walter from Germany, Finnish-made Sako and the Austrian Stayer Mannlicher.
The most famous and promoted biathlon rifles are “Anschutz”. It was to the management of this company that the German army biathlon team approached with a request to develop a rifle for biathlon, which would completely suit German athletes according to such criteria as convenience and recoil force. Thus, to create a new weapon, they used the best one at that time, Antschutz-54, improving it for a low-pulse central ignition cartridge with a caliber of 222.
Changing priorities
1978 is considered an important milestone in the development of biathlon. The transition to made this sport accessible and widespread. And the initiator of this significant event was the same German company “Anschutz”, which, by order of its compatriots, designed such a weapon. Countries whose athletes were the best in this sport, namely the USSR, Norway, Finland and the USA, did not want to lose their positions in world biathlon and move from military weapons to small-caliber.
Therefore, at the vote that was held with the aim of switching to a new caliber, there were not particularly ardent supporters of the new weapon. And then “political blackmail” was carried out by the Austrian side, which refused to hold the Biathlon World Championships in 1978 if the new weapon was not adopted. Three voters changed their original decision, and the scales tipped in favor of the new model.
Thus, the German manufacturer and athletes have become leaders in world biathlon, each in their own field. A unique standard for sporting weapons has been formed: the mass must be at least 3.5 kg, the caliber of a biathlon rifle must be 5.6 mm, better known as .22lr. The cartridges must be rimfire.
The consequence of the transition to small-caliber weapons was a decrease in the distance to the target - now it was 50 m. German biathletes won seven of the nine gold medals at the Biathlon World Championships in 1978, held under the new rules. Head coach USSR national team Alexander Privalov, a former medalist of two Olympic Games, blamed the disastrous performance of the USSR national team not on changing weapons, but on new look used skis and incorrectly selected lubricant.
An adequate response to rule changes
Gunsmiths and designers urgently presented the new Biathlon Bi-6 rifle, which is used in accordance with the new requirements.
The secret of such a rapid release of new weapons is explained quite trivially: just as in the early 60s, using the basis of the Mosin rifle, the Biathlon Bi-7.62 and Biathlon Bi-6.5 samples were developed, so in this time the designers took the ready-made versions of “Ural-5-1” and “Ural-6-1” and, through deep modernization, created the “Biathlon Bi-6”.
Rifle device
The biathlon air rifle is approximately the same for all manufacturers and differs only in the design of the components and some individual positions. In any case, all differences are regulated and strictly controlled. A biathlon rifle, the device of which consists of standard components and mechanisms, has a barrel, a wooden stock, a bolt, trigger, sight and magazine. The design of the butt allows, if necessary, to change its linear dimensions by installing additional spacers. A biathlon rifle sling is also required. Only the shoulder version is used, as this is the most practical option. The sight of a biathlon rifle must be diopter only; the use of an optical one is prohibited.
You can individually adjust and fit other parts of the rifle, for example, the “cheek” ( top part butt) and a belt with a hook for a swivel. The position of the weapon's center of mass can be adjusted by adding or decreasing balance weights. Quick reloading of the rifle, without changing the position of the athlete, is carried out using a crank mechanism, which locks the barrel bore using vertical axes of rotation.
Protective covers perform their function of protecting the barrel channel, weapon sight and front sight from various types of contamination. The design of the trigger mechanism allows you to optimally adjust the pressing force, the stroke of the trigger, as well as the nature of the trigger without disassembling the weapon. From the very beginning of biathlon, its rules stipulated that only a sliding bolt of a biathlon rifle was allowed, and only after the events of 1978 were they allowed to use models with a different design of this mechanism.
Anschutz shutter design
Each company that produces sporting rifles develops and produces weapons with its own bolt design. The German manufacturing company Anschutz uses a bolt whose design was developed back in 1935, constantly improving it.
Until 1984, all weapons of this brand were produced using a design with a rotating mechanism. After 1984, gunsmith P. Fortner installed a bolt mechanism on the rifle without warning, and this design is used on all Anschutz models to this day. Distinctive feature These devices are more compact in size and lack the lugs required for powerful cartridges.
Reloading the rifle is very simple, with two fingers: pulling index finger by the handle, the bolt is cocked, and its reverse stroke is carried out by pressing back mechanism with your thumb. Also, the reliability of the weapon during reloading is influenced by the ejector and extractor, which, due to their design, reliably perform their functions at low air temperatures.
Other valve designs
The Finns first used a new shutter design in their Finnbiathlon model, produced by Tampeeren Asepaja. The mechanism had a longitudinally sliding stroke and did not need to be turned.
Following them, the Bi-7 biathlon rifle also appeared in the Soviet Union, the bolt of which has the same design. It is impossible not to note the merits of the outstanding weapons designer Susloparov. In a short time, he was able to prepare the Bi-7-2 prototype for the Olympic Games in Moscow, which continued the development of sports weapons of the most famous Biathlon series. Speaking at the Olympics with a new model, the already well-known one won his fourth gold medal. Olympic medal in the relay race. By the way, on the next two Winter Olympics biathletes from Soviet Union With the help of this particular rifle they took gold in the relay race.
Development of Biathlon series rifles
Based on the most famous rifle “Bi-7-2”, in the early 90s the “Bi-7-3” and “Bi-7-4” models were developed and adopted by biathletes. The life cycle of these brands, with constant improvements, will last until the Winter Olympic Games in Vancouver.
Since 1991, the main supplier of weapons for biathletes, the Izhevsk Machine-Building Plant, began production of the new Bi-7-2 model. The biathlon rifle of this series is fired with .22lr rimfire cartridges, according to the standards generally accepted in 1978. Feeding occurs from removable magazines, the capacity of which is designed for five rounds. Also included in the standard kit are devices for additional ammunition, in the amount of three pieces. During the race, four magazines are located in a special cassette, which is attached to the butt of the rifle.
The barrel channel of this pneumatic is locked using a hinge-lever design.
The main criterion for shooting in biathlon is the rapid reloading of the weapon without changing the position of the biathlete and wasting precious time on new aiming. The cartridge is fed into the barrel of the Bi-7-2 rifle using a reciprocating motion thanks to a special handle. The shutter moves in a small arc during reloading.
The rifle is balanced, which is adjusted by adding or removing correction weights. Trigger force and trigger stroke can also be adjusted. The cheek piece on the butt and its length are adjustable and customized individually for each athlete, since accuracy depends on the athlete’s comfort when shooting. The barrel, front sight and sight of the rifle are equipped with special quick-hinged covers, the main function of which is to protect the weapon from snow, dirt and other contaminants that can affect shooting accuracy.
As already mentioned, the production of this brand of rifle has been going on for a long time, and throughout this time it has been subject to improvements and modernization. For example, today they produce the Bi-7-4A model. The letter A in the name indicates that this rifle is equipped with a barrel from the famous German company Anschutz.
Elite rifles
Elite ones include samples made to order for a specific athlete. The Bi-7-4 rifle in its ninth modification has a completely new stock, the settings of which can satisfy the requirements of any biathlete; a new diopter sight from the competing company Anschutz; ring front sight, which can be adjusted. To protect against corrosion and improve performance, the receiver and barrel are chrome-plated. Among other models of elite rifles, the Antschutz 1827 stands out, which is called “the best of the best” by many champions and biathletes.

Is it designed like a hunting one or a sports one?
Is there a special communication service available?
alexei2015 27-08-2015 15:14
The rifle was purchased under a hunting license. I can send it via “special communication” to a hunting store in your city if you agree with the store so that they receive the rifle via “special communication” and re-register it in your name.

If the rail was made for a diopter, then the quality is most likely at the same level, if you decided to install optics on this rail, then blockages are possible, the requirements for rails for optics are higher, but with most Soviet rifles such a task was simply not set

If he’s so intelligent here, why did he shit on other topics without thinking? Don’t sell him the Bi-6, when I sold the Ural-2, bought for the occasion and not used without shooting, on the basis of which the Bi-6 was created, so much poop spilled out of this pepper that it was a shame to even answer))) it was not clear to him that there are times when there is no time to run around the shooting ranges, but here it’s politeness itself)))

Kalo Machine Gun Maxim, glad you remember. By the way, let's return to the topic about narrowing? Here one competent and respected person told me:
"ask where a slight tension is felt when the bullet moves. If the barrel is more or less, then you can feel it in the middle and at the end, they all had small chokes."
By the way, bring up the topic about your Ural... You didn’t hear anything bad from me about the rifle, but your harsh judgments... In general, they are visible here too.
Maxim 05-09-2015 16:00
By the way, let's return to the topic about narrowing? Here one competent and respected person told me:
Why go back then? In my own topic, it quickly became clear to me that talking with boorish clowns who repeat other people’s tales is a waste of time, and here a new round of your tales about chokes will only litter one more topic with nonsense. So don't even offer it)))

And then you wanted a bi-6, so why are you embarrassed, offer this seller a competition in the shooting range of this rifle with your air gun, tell him that this rifle should have a choke, and without it it is a complete mess, as one smart friend told you. Then buy this rifle and send the seller a photo with the background of beaten crows so that he knows how great you are
P.S. Please note, I’m not trying to outbid the rifle, I’ve had the Bi-6 for a long time, I’m just advising the seller not to give away an exceptional rifle to just anyone)))
sportgun 06-09-2015 15:59
It’s in vain that you “Machine Gun Maxim” are talking so much about chokes, having worked at one time in the National Team Bullet shooting, I had to get stuff out of a variety of barrels, from 4.5mm to 7.62mm. And bullets stuck and nails, too many to list....
So I can tell you with confidence that Soviet sporting rifles had chokes, a very small tension when the lead bullet moved at the end of the barrel, and of different lengths, apparently depending on the year of manufacture and the firing rate of the rifle.
And every competent trainer did this first of all, with an inspection of the bullet, before putting the rifle on the line and starting shooting.
Best regards, Maxim
Maxim 06-09-2015 17:35
Every competent coach can at least walk on his head, as long as he gives results. At the moment, the presence or absence of a narrowing is not a qualitative characteristic of a rifled barrel. The rifle can shoot great with or without a constriction. And it can also shoot poorly if it has a narrowing. And in general, as an engineer, I believe in documentation and instrumental control. Attempts to measure constriction by pushing a bullet are not far removed from cleaning guns with a brick.
sportgun 06-09-2015 20:42
I agree that there are calibers, but there aren’t! Therefore, this is one of the simplest remote ways for us to check.

Gentlemen, the only thing that’s stopping me from picking up the rifle is our beloved TsLRR, which is a little behind the times for obtaining a license to purchase a rifled long-barreled hunting rifle.
Sportgun, do not enter into controversy with nyJlemeT Maxim. The person has a blinkered look. In principle, he is not interested in listening to his interlocutor. It's more important to write something. So talking to him is pointless.

Hello everyone! At one time I was involved in biathlon, and the first rifle was BI-6. They all shot for less than a minute, and this was lying on the line, without a machine.

I drove the Fraser with a BI 6 and SM micrometer to cut the fins, but both boxes were crooked, they couldn’t set them to zero, I had to make a slight tilt, well, like for the firing range. And the hardening of the boxes is not uniform, it is wavy. So much for the vaunted Soviet quality. Although they are big and even more so, the rifles are gross, so what can you want from them. Not Germans in a word.

Alexander, have you measured the hardness of the boxes? And the Germans too?
The box is not heated. The blank for the box, like any other steel product (a solid solution of carbon in iron plus alloying elements), undergoes heat treatment to give it the required properties. Unevenness may be a consequence of the characteristics of the technological equipment where the heat treatment was carried out. This is unlikely to have any effect on the consumer properties of the rifle. The crookedness of the box is also not particularly noticeable. The diopter is set perfectly, maintaining stp. Although this is not so important, because for each position (standing, kneeling, lying down) you still need to shoot.
Please tell me, does the BI-6 have a shorter barrel than the Ural?
alexei2015 12-09-2015 09:25
Barrel length: BI-6 -600 mm, Ural-2 - 680 mm, Ural-6 - 680 mm, Ural-5 - 700 mm.
Barrel diameter: BI-6 - 20 mm, Ural-2 - 22.5, Ural-6 - 22.5 mm, Ural-5 - 24 mm.

I wonder if the BK series of rifles are of better quality? I'm especially interested in the dovetail. Is it made accurately or do the rings need to be ground in?
And the rifles leave a feeling of powerful construction!
Maxim 15-10-2015 12:46
On BC, the dovetail is intended for optics. On bi-6 no. Draw your own conclusions from this.
But the rings need to be ground in anyway, what does the dovetail have to do with it if they are ground in on the scope tube and not on the mount???
Lomaster 15-10-2015 15:21
But why then do you constantly talk about it?
The dovetail has a certain geometry and that’s it, even a diopter, even put optics there. Whether on the bk or the bi-6, the dovetail is made with the same quality. The only thing is that not all bi-6s have a dovetail for the entire length of the box.
On mine, for example (late export version) - the full length, on others - the dovetail is cut short. There are no other problems.
Blue beret 15-10-2015 16:58
Maxim 15-10-2015 18:22
Dear Pulemet Maxim, you don’t have a Bi-6, right?
But why then do you constantly talk about it?
Wrongly respected. I have Bi-6 as well as BC. So I know what I'm talking about. Keep your advice to yourself, I’ll somehow figure out what to write and what not to write without you.
quote: Originally posted by Lomaster:
Then the Bi-6 doesn’t have a constriction in the barrel at the exit, now you have some conclusions that its dovetail is not for optics...
whether or not there is a narrowing in the trunk of the small fish is not important. No dependency good fight rifles depending on the presence or absence of carrots. Everyone is fooled by this at first, and I also once tried to get a rifle with a narrowing, but practice has shown that all this is dancing with a tambourine. So leave these legends from pneumatics for their section. And the fact that the BI-6’s dovetail is not for optics is clear to any normal person, since the discipline was shot from a diopter sight. If you don't understand, that's not my problem either.

any amateur has the right to have his own opinion, and to be honest, I’m too lazy to refute your nonsense, which is a consequence of your technical illiteracy. There is such a thing called quality. It determines tolerances and fits when performing any procedure. And to claim that the mounting surfaces for the diopter and for the optics are made with the same quality can only be an ignoramus like you, dear. If by quality you mean the surface roughness or the milling angles of the side surfaces of the dovetail, then yes, they can be very similar to the eye, and when painting the rifle they look little different. But on the BC, the dovetail of the optics must have a much more accurate alignment with the barrel than the dovetail of the diopter on the Bi-6. And the master performing the milling operation when working with BC has much more requirements than during a similar operation with Bi-6. It's like in simple words about simple things that for some reason you don’t understand
quote: Originally posted by Lomaster:My bi-6 now has optics from BC, on the original crown, there are no problems.
Your Bi-6 has the most primitive and cheapest BC sight, namely the dinosaur TO-4, which in the original has a specific thick stump and can only be used to shoot at stationary targets, perhaps at a bucket. I can’t imagine what problems there might be with it, you can carry a rifle with it and not have any problems with it either. You really can’t crack nuts with this sight; it still has a luminescent body, and this should be a minus for you.
There’s no point in talking about accurate shooting from this scope at all, which means your opinion with such optics, in principle, cannot have any meaning

Lomaster 15-10-2015 19:37
It is clear that you are indifferent to everything. And the rifle should be kept in a safe, like all experts probably have. I measured the barrel with calibers and have an idea what I’m talking about. And then you modestly take the conversation aside, saying it doesn’t matter whether there is a narrowing there or not. They have already provided a link to a topic where they zealously assured that there is no narrowing in bi-6. And it exists.
I don’t understand why all the writing about TO-4. It was clearly demonstrated to you that the original BC sight on the original crown fits on the bi-6. What does the thickness of the hemp and other obscurities of the sight have to do with this? No answer.
The sight is simple and reliable, it performs the function of shooting at 50-100m and is fine.
Such competitions were won with such sights...
What you stated about the alignment of the dovetail for optics and for the diopter and milling masters is reluctant to disassemble.
A worker stands at the machine and inserts a workpiece - whack - makes a groove, inserts a workpiece - whack - makes a groove. Moreover, blanks for both bk and bi-6 are in one heap, figuratively one might say.
In general, I won’t argue, you know better. Those. sorry, more indifferent.

The best of the interesting
Since it is still interesting to clarify the question regarding sporting rifles missing from the cadastre, I wrote out an appeal asking for a competent answer.
A citizen who is a pure hunter has the right to own such a rifle, if he is not an athlete or something.
And the second case is when the rifle is listed as a sporting rifle in the cadastre, but was registered, say, in the name of the owner before the changes in the law on weapons. What then? The law doesn't have retroactive force, does it?
Let's see what they answer. Otherwise, who gets Bi-6 for ROH, who doesn’t get an extension, who gets what...

What will they answer?? ..That the plant produced, for example, according to technical documentation and other documents, a sports rifle for winter all-around, and after 10-20 years this rifle just suddenly became a hunting rifle?? It’s simple - the Plant did not produce the Okhotnicha Bi 6, but produced the Sports one, which it still is. According to the documents.
Are we talking about this??
Cadastre and so on have nothing to do with it..

Because of this treatment, no one will worry, don’t worry, it’s only me who is at risk. It is written there correctly.
Let's wait for an answer, then we will draw some conclusions. They should give an answer within a month.

They will tell you that there is a cadastre, if it is not in the cadastre, then there must be a certificate, if the rifle was manufactured before 1994 and is not in the cadastre, then it is not a sporting rifle. It cannot be otherwise. Why shake the air? Consultant+ helps.

“Optical sights are those that consist of a system of lenses in a metal frame (body), for aiming in which sighting threads instead of a front sight are used.
On rifles for target shooting "Running deer" and "Running boar" are usually installed optical sights: TO-4, which has a fourfold magnification, TO-6 - sixfold and TO-6P - with a variable magnification from one and a half to six (Fig. 13). Nowadays, among leading athletes, optical sights redesigned on their own are widespread - with two aiming stumps (double-stump), separately moving by additionally installed handwheels (drums)."

Bullet sport shooting. Ed. 3rd, revised and additional M., "Physical education and sport", 1973.
Try reading something newer. A lot has changed since 1973.
And leading athletes have not been engaged in “redesigning sights on their own” for a long time.
The BK-1 and BK-2 were equipped with diopter sights with a reversible front sight, and the BK-2M, BK-3 and BK-5 were equipped with optics with two stumps.
Sincerely.

Yes I believe. It’s just that all this did not appear all at once, but through long evolutionary development and selective selection.
So what about photo sights? Are you selling or not?

I raised this question when I handed in the documents for registration of the biathlon-6 rifle last Tuesday. Yesterday I took the permit. Therefore, you don’t have to believe me, you don’t have to believe Consultant+, you can send your question to the Ministry of Internal Affairs. However, the fact remains a fact. In most cases, everything works out fine. If difficulties arise, contact a good lawyer and outline the situation. Let the lawyer work.
The biathlon rifle began its evolution in 1948, when the International Federation of Modern Pentathlon appeared. At the same time, the biathlete’s cartridges have not changed since 1888 - 5.6 caliber, rimfire, with a small amount of gunpowder. This cartridge gives low recoil, which is important for accuracy and accuracy.
But there were different designs and manufacturers of rifles, but today the vast majority of biathletes compete with the Anschutz-Fortner 1827F (price from $3,000). Even Russian athletes They often refuse domestic products in their favor, although at the Olympics in Vancouver (and, of course, at the home Olympics in Sochi) they performed with Izhevsk Bi-7-4 from the Biathlon series.
Technical characteristics of the Anschutz-Fortner rifle for biathlon:
- Weight - 3.63 kg;
- Barrel length - 730.25 mm;
- Total length - 1,041.4 mm;
- Caliber - .22;
- Magazine capacity - 5 rounds;
- Walnut stock, adjustable cheekpiece, adjustable trigger.
Professional rifle models should not be confused with solutions like IZH-61. However, for training there is a separate series of BI-7 rifles, made at Izhmash. A modern BI-7-5 costs around 90,000 rubles. It is more convenient for a young biathlete to get used to it small arms. The caliber of such pneumatics is not 5.6, but 4.5 mm.
The pneumatic "Biathlon-7-5" is built according to a weapon design with preliminary injection of a high-pressure cylinder (PCP) and is used in summer and children's biathlon. In terms of weight and dimensions, it corresponds to BI-7-4, so you can train with it even in a regular pneumatic shooting range. The firing range is 10 m, charging the cylinder is enough for 200-250 shots. Bi-7-4 and Bi-7-5 weigh 4.5 kg. Compared to their predecessors, the rifles have “lost weight” by 500 grams.
Technical characteristics of the Biathlon-7 rifle:

| Trigger force adjustment limits, kgf | 0,5...1,0 | 0,5...1,0 |
| Store capacity, pcs. cartridges | 5 | 5 |

The Biathlon-7-4 sports rifle is a small-caliber (small-caliber) rifle chambered for 5.6 mm (.22LR). The rifle is considered a men's rifle. The butt length is adjustable. The rifle is produced for right-handers and left-handers, there is an option with a safety lock.
At the Olympics in Sochi, Russian biathletes competed with BI-7-4
Special rifle biathlete appeared in the USSR in 1958. BI-7 with fast direct reloading, modified BI-7-2, BI-7-3, which became the main one for Russian biathlon rifles.
The main innovative feature of the professional BI-7 was the crank-type locking mechanism with vertical axes of rotation. As a result, it was possible to achieve a quick reload with minimal disruption to the athlete’s preparation. An experienced shooter fires at the speed of a self-loading weapon, which at one time dramatically improved the achievements of Soviet biathletes. The rest of the rifle's design is traditional. It is possible to adjust the trigger mechanism and the nature of the descent without disassembling. The sight is mounted on a quick-release diopter.
IZH-60/61 are not professional rifles for biathlon
OJSC IZHMASH biathlon products are divided into men's, women's and junior biathlon products. 7-4, 7-4A, 7-5 are recommended for men. 7-3 and 7-3A for women and juniors. In terms of design, all rifle models are created on a single design basis. The only differences are in the size of the stock and the position of the trigger relative to the handle.
A biathlete spends 1000-1200 rounds of ammunition per month
The Biathlon-7-3A and Biathlon-7-4-A rifles use German Anschutz barrels. In addition, two more sporting weapons companies Steyer Mannlicher (Austria) and Walther are represented on the market. Taking into account the distribution of shares, it can be argued that practically modern biathletes shoot from German rifles. This is such a monopoly!
It is interesting that the first three-time medalist in the history of women’s biathlon Olympic champion world and five-time, being German, she preferred the Russian Biathlon-7.
Rifle device
The base model for developing the design of the BI-4 rifle was a well-proven model of a small-caliber sports rifle"SM-2", the device of which was described above. Therefore, we will focus only on the differences of “BI-4”.
At the bottom of the front sight there is an L-shaped protrusion with two threaded transverse holes for fixing screws and one longitudinal hole for the axis of the barrel cover, which protects the barrel and the upper tube of the front sight base from snow. The cover axis is fixed with a pin. A pin is attached to its front end for connection with the cover and its spring. There is a groove at the top of the front to fix the position of the cover, which is stamped for this purpose.
The thread for the nut, which secures replaceable front sights and improves aiming conditions, has been moved to the rear of the base. The nut itself is 3 times longer than on the SM-2. It has two holes for screwing and unscrewing the nut using a drift.
The receiver at the bottom in the front part has a longer window, which houses: the trigger mechanism at the rear, and the insert, magazine and magazine latch at the front. The right wall of the box also has a cutout that is interrupted in the area of the groove for the base of the handle.
The box insert is an L-shaped spatial part with a figured window in the upper part for the passage of the store. In front of it there is a protrusion for fixing the liner in the receiver and a rectangular groove for the passage of cartridges when dispensing them from the store. At the back of the liner there is: at the top - a slot for the passage of the bolt rammer and an oval hole that forms a hard reflector on the liner; below there is a rectangular protrusion with a hole for a pin, the front plane of which is a guide for the magazine.
The magazine latch is located in the receiver socket and moves in it. It is a rod with a tooth that holds the magazine by the body. A spring and a washer are put on the cylindrical part of the latch, after which the end of the latch is flared, forming a permanent connection. To activate the latch there is a button located with right side forend in a special socket.
The BI-4 shutter differs slightly from the SM-2 shutter. Due to the presence of the magazine, its semi-cylindrical part is longer, and the forwarding protrusion runs along the entire length of the front part of the bolt. Only a cylindrical striker is used, so the channel for it remains the same as on the first SM-2 models.
In the trigger mechanism, the sear in the upper part has a slot for the passage of the rammer; On the trigger there is a socket in the upper part in which its spring is placed. Additionally, a pressure screw and a warning screw have been introduced into the adjustment unit, and the design of the force screw has been changed, which allows you to configure the trigger mechanism to operate “with a warning” or to operate with a “smooth” descent. In the first case there should be a gap between the bend and the trigger, in the second there is not.
The magazine is box-shaped, replaceable, and consists of a stamped-welded body, a plastic feeder, a feed spring and a cover with a stopper.
The magazine body is a box, at the bottom of which there are bends for the magazine cover. The position of the lid in the magazine is fixed by a stopper (a plate with a protrusion) that fits into the hole in the lid. At the top of the magazine body there are bends that ensure the cartridges are held in the magazine in a certain position, and protrusions that provide the direction of movement of the cartridges when they are chambered. On the left wall of the magazine body there is a cutout for the latch tooth that holds the magazine in the receiver. To increase the rigidity of the body, two longitudinal corrugations are extruded on its walls, which also provide the direction of movement of the cartridges.
The stock of the BI-4 rifle has the following differences. There are two deep cutouts at the top of the forend to make it easier. The through window is long enough for the store to pass through. On the left side of the forend there is a cutout for attaching a special strap, in which the front sling swivel is secured for carrying the rifle when cross-country skiing. On the right side of the forend there is a hole in which the coupling for the magazine release button is fixed.
The buttstock is not adjustable in length; nor in height, so the back of the head with rubber is attached to its end.
The safety bracket has an additional window in front for the passage of the magazine with a recess (in front) for easy removal from the receiver.
Operation of mechanisms
When charging Having taken a position at the firing line, it is necessary, first of all, to open the cover on the base of the front sight, turning it down and joining the barrel. Then insert a magazine filled with 5 rounds into the receiver slot so that the magazine latch clicks. Next, turn the reloading handle up and remove its stop from engagement with the cutout of the receiver, i.e. unlock. When you turn the bolt frame, it will move the trigger back with its spiral, and the latter will compress the mainspring and stop at the cutout area.
Pull the bolt back all the way to the bolt stop, while the rammer protrusion will come off the neck of the magazine, and the first cartridge, under the action of the spring with the feeder, will rise up and rest against the bends of the magazine.
Push the bolt forward by the handle. He will grab the cartridge with his rammer and squeeze it out of the bends of the magazine into the chamber. When reaching the extreme forward position, the edge of the sleeve jumps over the hooks of the ejector and ejector, the trigger stops at the cocking of the sear. By turning the handle down, we insert its stop into the cutout of the receiver, i.e. Let's lock the shutter. At the same time, the frame spiral will also unfold. The trigger will move forward a little and stop on the sear. The rifle is loaded and ready to fire.
When shooting . Point the rifle at the target and gently pull the trigger. If the trigger mechanism was configured for a “smooth” descent, then when you press the trigger, the force of two springs (trigger and force spring) will “change smoothly. After the front shoulder is removed from under the sear, the latter will be squeezed out by the cocking of the hammer under the action of the mainspring. The hammer will move forward and strike the firing pin, which will move forward and break the primer of the cartridge.
If the trigger mechanism was set to release “with warning,” then there was a gap between the pressure and the front shoulder of the trigger. Therefore, when you press the trigger, at first only the force of its spring will be overcome, and then, after selecting the gap, the force of the oppression spring will be added. A sharp change in force will be a signal that the trigger will soon come off the sear.
For the next shot, all these steps must be repeated. In this case, when the bolt is pulled back, the cartridge case will be removed from the chamber by the ejector and ejector, and when approaching the reflector, it will hit it with the bottom and fly out of the box with additional help ejector. The next cartridge in the magazine will rise and rest against the bolt chamber. When the cartridges from the magazine are used up, the latter should be replaced. To do this, press the magazine release button on the right side of the forend and remove the magazine from the receiver (it should come out easily under its own weight).
Disassembling and assembling the rifle
60s
Biathlon cannot be considered one of the old-timers of the Winter Olympic Games. It was first introduced at the 1960 Olympics in Squaw Valley, and the debut world championship was held two years earlier. Initially, weapons were not strictly regulated: the rules allowed the use of repeating rifles of 5.6, 6.5 and 7.62 mm caliber. As you can see, the cartridges are quite powerful, but the fact is that the shooting was carried out from a much longer distance: 150-200 meters instead of the current 50.
One of the first questions that biathletes had to answer was the choice of caliber. As a result, two options were presented to the court. First: rifles of 6.5 and 7.62 mm caliber, which had greater accuracy, accuracy and less dependence on weather conditions, which at that time was especially important given the high cost of a miss. Second: their small-caliber brothers 5.6 mm, lighter, not so much interfering with the athlete’s movement along the track. In the USSR, the choice was made in favor of the accuracy and caliber of 7.62 mm. And a year after the 1960 Olympics, production of domestic specialized biathlon rifles “Biathlon-59” began, which were created on the basis of the Mosin rifle. The designer was A.S. Shestryakov. The weight of such a rifle was about 4 kg, length - 1.23 m, bullet range - 3 km, magazine capacity - 5 rounds.
70s
Almost until the end of the 70s, athletes in most countries relied on various modifications"Bi-59". But as the years passed, new experiments were carried out. It is clear that everyone wanted to eat the fish and not choke on the bone. The point is that the designers tried to create a lighter weapon that at the same time would allow accurate shooting. The initiative in this matter came from the German company Anschütz, the main competitor of Izhmash, which proposed to finally switch to a small caliber. This was supposed to make biathlon more spectacular and economical by reducing the size of the shooting range, and also allow children and women to be involved in this sport. The arguments turned out to be convincing, and in 1977, the congress of the International Pentathlon and Biathlon Federation (then these two sports were united) adopted new rules, according to which a small-caliber rifle chambered for 5.6mm became the standard weapon, and its standard was the Anschutz-54.
80s
Izhevsk designers responded quite quickly to their competitor’s new product and a year later introduced the BI-6 rifle chambered for a rimfire cartridge. For a long time, biathlon rules allowed the use of weapons only with a longitudinally sliding rotary bolt, but due to the arms race, the ban on rifles with rapid reloading was eventually lifted, which, as you understand, significantly increased the rate of fire.
Immediately after the lifting of restrictions on rapid reloading, Izhevsk presented its new model BI-7, which instantly became the most popular. Not only domestic, but also many foreign athletes, including representatives of the German national team, sought to get this rifle, especially since Anschutz modernized the reloading mechanism on its models only in the second half of the 80s. Subsequently, the stars of the German national team performed with the Russian “BI-7” at the largest competitions: Frank Luke, Alexander Wolf and Kati Wilhelm.
Technical characteristics of BI-7-2: caliber - 5.6 mm, weight - 4.5 kg, total length without hook - 1050 mm, barrel length 500 mm, magazine capacity - 5 rounds.
90s - 2000s
Based on the “BI-7-2”, which became an absolute hit in the 80s, the following models were created - “BI-7-3” and “BI-7-4”, which were used by athletes in the 90s. And after a little modernization, these rifles survived until the Olympic Games in Vancouver. However, in the 90s, Russian rifles faded into the background. Anschutz turned out to be an almost complete monopolist in terms of biathlon weapons. The main reason is that perestroika and post-perestroika collisions did not bypass the Izhevsk plant. Much was lost at that time, including the quality of domestic barrels. Because of this, as well as constantly arising problems with service, almost everything, including Russian biathletes, switched to Anschutz rifles.
The main feature of the Anschutz was fast reloading. Cocking was carried out with the index finger on a special handle, and the bolt was returned back by pressing with the thumb
to its back. Anschutz rifles have a rather interesting procedure for assembling the rifle: barrels, receivers and triggers are sent to the city of Rohrdorf, where the company is located Peter Fortner, a gunsmith who patented a rifle he invented in 1984. In Rohrdorf, the parts are carefully fitted to the valves, and then, assembled, they are returned back to Ulm on the Anschutz. Next, the barrel, receiver with bolt and trigger mechanism are mounted in the stock, and a diopter sight and ring front sight are installed.
The barrels are produced by the Anschutz company itself. When using them, high-quality steel is taken, and various tests are carried out for frost resistance and corrosion resistance. Now even in Russian rifles barrels from a German manufacturer are used.
Technical characteristics of BI-7-4: caliber - .22 Long Rifle (5.6×15 mm R - small-caliber unitary rimfire cartridge of 22 caliber (5.6 mm), weight - 4.5 kg, Dimensions: 1050x90x290 mm , barrel length: 500mm, rifle price - 80-120 thousand rubles (elite version).
Technical characteristics of the Anschutz 1827F: caliber - .22lr, weight - 3.7 kg, weapon length: 1040 m, barrel length: 550 mm, number of rifling: 8, rifling pitch: 355 mm, rifle price - 250-310 thousand. rub.
If you take a look at the Russian team, they use domestic rifles (Izhmash Bi-7-4): Olga Vilukhina, Evgeniy Garanichev, Ekaterina Glazyrina, Yana Romanova.
And with Anschutz 1827F rifles: Evgeny Ustyugov, Ivan Tcherezov, Alexey Volkov, Alexander Loginov, Anton Shipulin, Olga Zaitseva, Ekaterina Yurlova, Svetlana Sleptsova.
