GUN STOCK Russian patent published in 2014 - IPC F41C23/16 F41C7/00 

FIELD: weapons and ammunition.

SUBSTANCE: stock of small arms like "bullpup" automatic weapon with a carriage is made based on a metal enveloping guide for a moving firing unit with possibility of its preliminary roll-out to perform a "fixed string" of three-four shots.

Elements facing downwards and arranged on lateral sides of the metal base of the firing unit prevent movement to sides of bends of the enveloping guide of the gun stock.

In the muzzle part of the stock there formed are side connection elements for arrangement under the fore-end of "bayonet-knife" attachment elements or an under-barrel-mounted grenade dispenser, which are attached onto the guide gun stock.

EFFECT: improving stiffness of a gun stock and reducing deformation loads at shooting.
