Shotgun Bekas M Auto has been created in Vyatsko-Polyansky engineering plant "Molot" in 2002. This gun is not the first among the domestic self-loading rifles with fixed barrel and also is not a new development. This shotgun was created based on already-proven rifle Bekas Auto, which, in turn, was constructed in 1997 on the basis of the shotgun Bekas. The fact that Snipe Auto had some flaws in automation and USM, which was soon rectified, and a new, upgraded rifle received the name of the index M.
Bekas M Auto, like its predecessor the Auto Bekas refers to the classic self-loading smooth-bore hunting guns integrally cast with a tubular magazine under the barrel.
When fired, the energy of the powder gases passing from the barrel bore to the gas chamber drives the gas piston, which is a ring around the store. The piston thrust by driving a shutter, which opens when you roll back needs to extract the cartridge case through the window of the receiver after its interaction with the reflector, grenade shop served the new cartridge on the tray, and the shutter cocking trigger the trigger mechanism of the gun. On the return stroke the bolt picks up the cartridge from the tray and docile it into the chamber. The return spring of the spiral, put on and store compressed gas by the piston during its backward motion.
Locking and unlocking of the trunk takes place by means of swinging larvae located in the gate. The larva enters into the groove in the shank of the barrel, thereby providing a rigid grip. Therefore, in the time of the shooting burden falls on the host, not on the receiver. In the result, the receiver is not required to make steel, material for it is aluminum alloy.
One of the notable advantages of an upgraded version of the Bekas M Auto can be called "smart" port. This provides stabilization of the pressure of the powder gases on the piston during their withdrawal, which occurs automatically, thanks to being in the gas chamber site. This leads to the fact that the shotgun becomes relatively softer, the momentum transferred to the piston stopper, stabiliziruemost, when shooting using a variety of cartridges, whether 12/70 or 12/76 Magnum. This node is assembled into the front end of the magazine tube, resulting in impossible to install extensions that increase its capacity, representing only 4 of the cartridge.
