RECEIVER FOR FIREARM CONTAINING BARREL CONTROL MECHANISM AND TRIGGER MOUNTING SUPPORT Russian patent published in 2002 - IPC

FIELD: small arms, applicable in automatic pistols that use plastic receivers. SUBSTANCE: the firearm receiver is made of plastic material, has rail guide members for the slide positioned in its front, central and rear parts. The receiver is suitable for the barrel part of the weapon, which shifts backwards and downwards due to the displacement of the slide and with the aid of a cam member that stops the barrel movement with the aid of the walls of the pocket made in the receiver. The force and the energy produced at the stop of the movement of the barrel and the cam member backwards and downwards are transferred to the receiver, when the cam member encounters the receiver pocket. The receiver and the cam member have openings passing the locking pin for the slide. The locking pin also facilitates the transfer of energy to the receiver. The forces under the action of which the slide rushes upwards at a stop of movement of the barrel and cam member are suppressed with the aid of the rail guide members. The trigger turns round its support positioned in the receiver pocket below the cam member. EFFECT: enhanced reliability of weapon functioning. 14 cl, 10 dwg
