PLATFORM FOR SMALL ARMS Russian patent published in 2020 - IPC F41C23/00 

FIELD: machine building.

SUBSTANCE: platform for small arms consists of coupling, impact mechanism, lowering, safety lock, Picatinny rail, which is rigidly attached to coupling, descent transfer assembly, fuse transfer assembly, release transfer bus and safety lock. Platform is a monolithic part with structural elements made in it, in which parts of the descent transfer assembly, parts of the fuse transfer assembly and the trigger mechanism are placed. Transfer bar is rigidly fixed to coupling by means of handle screw, and transfer of lowering of trigger mechanism is made in form of traction rod. Coupling has inner cylindrical surfaces corresponding to diameters of the protrusion of the rifle box of the rifle and the base of the barrel, and a key which is brought into the hole in the coupling of the corresponding shape, located coaxially to the cylindrical hole of the barrel receiver.

EFFECT: technical result is improvement of firing accuracy and absence of displacement of middle aiming point at various methods of rifle retention at the moment of firing, reduction of rifle length without change of barrel length, improvement of rifle balance, displacement of rifle mass centre to rifle shoulder, easier control of lowering and fuse.
