BIZON Submachine Gun

Video > http://club.guns.ru/images/video/bizon.rm

In 1993 Victor Kalashnikov (http://www.guns.ru/gallery/designers/kalashnikovvm.html) and Alexey Dragunov (http://www.guns.ru/gallery/designers/dragunovae.html), engineers of the IZHMASH JSC (http://www.izhmash.udm.ru/), located in the city of Izhevsk (http://izhavsk.ru/), Western Urals, Russia, created a novel submachine gun designated BIZON (Bison). 60 % of the BIZON components are interchangeable with the AK-100 (http://club.guns.ru/eng/ak100.htm) series assault rifles. Depending on the specific requirements of Customers, BIZON may have different constructions of the rear sight and the buttstock. The rear sight of BIZON-2 (http://www.izhmash.udm.ru/arms/bizon2.html) is similar to that of the Kalashnikov sliding tangent-type with three divisions of scale for 50, 100 and 150-meter elevation. BIZON-3 features a pop-up dioptric rear peep sight, with protective ears. The buttstock folds upward to lock into a spring-loaded latch ontop the receiver cover. A number of modular muzzle devices is available to meet requirements of specific tactic missions: silencers, muzzle brakes, compensators, flash hiders, etc.
The front sight of the latter two versions - BIZON-2 and BIZON-3 - is a derivative of the AK-74M (http://www.izhmash.udm.ru/arms/ak74m.html) construction, while the first configuration of the BIZON has the front sight similar to SVD - the Dragunov sniper rifle (http://club.guns.ru/eng/dragunov.html), with protective hood.

The BIZON trigger mechanism is exactly that of the AK74M.
The synthetic 64-round helical-type magazine provides an easy procedure of loading - all cartridges are oriented nose forward and can not be loaded incorrectly.
The latest modification of the magazine has four openings in the right side, with markings 4, 24, 44 and 64 to show the number of rounds in the magazine.
Construction of the stock makes the BIZON SMG a very controllable weapon afield.

BIZON-2, with extra magazine.

Judging by the results of numerous tests, the BIZON is capable of highly accurate and accented penetrating fire. Taking into account its cyclic rate varying from 650 rpm to 700 rpm, depending on the two types of the used ammunition, it makes a desirable weapon in various tactic missions.
As estimated by experts, the BIZON SMG may be successfully employed by the Law Enforcement and Anti-terrorist units where fire contacts are of rapid and intensive nature, where multiple targets are to be engaged at short intervals of time, at the range of not exceeding 100 meters. In such situations the following BIZONs characteristics may play an important role:
high hit probability;
excellent controllability in a fully automatic fire;
enhanced accuracy of rapid (instinctive) fire;
compact envelope and a possibility of carrying in concealment;
large capacity of magazine;
variable operational range of fire.Army and Special Forces are also looking for a compact, effective weapon to be employed in surgical operations where fire of high density and accuracy at short and medium ranges is required. Being engaged in a combat, frequently conducted under complex environmental and operational conditions, a soldier needs a lightweight, low recoil firearm which may benefit by an operator-s lesser fatigue as well as by a possibility of conducting fire on the move or from shelters.

BIZON-2, field-*****ped.

BIZON is exactly the weapon, which can meet such challenges. It can be comfortably fired from various positions: (a) with the extended buttstock at the shoulder, (b) with buttstock folded, from the hand (as a pistol) or from two hands, with carrying sling looped over the shoulder.

All modifications of the BIZON-series have the following operational modes: safety, semiautomatic and fully automatic. Change of modes is achieved by placing a selector lever into a required position.
When placed into its uppermost position, the selector brings the weapon into safety. The trigger is blocked and the bolt carrier could be retracted only partially - just enough to see through the opening whether there is ammunition in the magazine. The amount of travel the bolt group performs is not sufficient to **** the hammer and send the first round into chamber.
Shifted into extreme low position marked "OD" (odinochniy means single in Russian), the selector brings the systems into a semi-auto operation. Upon firing, the bolt group being driven rearward, the extractor claw removes an empty case from the chamber, and the ejector disposes of it through the opening in the right side of the top cover. As the bolt carrier travels farther, the single-strand recoil spring is compressed, the hammer is cocked and engaged with the auto-safety cocking cam. This cycle completed, the bolt group begins its return travel driven by the recoil spring. The mechanism goes forward, another round is *****ped from the magazine and chambered. The bolt carrier releases the hammer from the auto-safety sear. The hammer cocked the bolt in the front position - the http://club.guns.ru/images/bizon-3-sm.jpg (http://club.guns.ru/images/bizon-3.jpg)
BIZON-3, buttstock folded.

submachine gun is ready to fire. The trigger mechanism's mainspring is of multiple-strand type, which lasts longer and offers better performance. After the trigger has been released, its extension moves forward. The hook in the trigger extension is held by the sear. When the trigger is pulled, its hook moves the sear and disengages it from the hammer-cocking cam. The hammer, actuated by the mainspring, pivots forward and strikes the firing pin. The firing pin moves forward and impinges the primer. Another shot is fired. The cycle is completed.
To fire in full-auto mode, the selector should be placed into the middle position marked "AB" (avtomaticheskiy). By doing so, the sear is deactivated and does not control the hammer. In this mode the auto-safety sear holds the hammer back until the bolt carrier while moving forward releases it to fire another round.

Valerie Shilin did an article about it in SOF mag about 10 years ago.

He found that the low power standard Makarov ammo had the highest rate of fire while the more powerful ammo types recoiled the bolt back further almost to hit the rear of the receiver which resulted in a lower rate of fire for that ammo.
Just for show one guy emptied a whole 67 round mag (it might say it takes 64 rounds but that is only because Makarov ammo comes in boxes of 16 rounds and 64 equals an even number of boxes) into a target at 50m and all the rounds hit within the chest area.

Is the Bizon in use by any Russian armed forces/services? Army? Spetsnaz? OMON? Police ?

Any exports?

PM Romans for that one, he will probably have a pic to back it up.

Last I hear, the Bizon is dead in the water for lack of interest from the government. It's an interesting weapon, but given the track record of other Russian SMG and PDW weapons that did not go beyond test batches or even singular factory samples - not surprising...

Bizon/Bizon 2 is still being manufactured, and is used by "special" police/federal agencies. Not army.

I've done that myself. Right after Viktor Kalashnikov emptied his for a friendly competition
