PISTON LONG-STROKE GAS-OPERATED RECOIL AUTOMATIC SYSTEM FOR MEDIUM-LARGE-CALIBER HIGH-PRECISION AUTOMATIC RIFLE

摘要

A newly designed automatic system aims to solve the problem of low precision of medium-large-caliber automatic rifles. With an AK47 automatic assault rifle as a reference, the new automatic system also uses a rotary locking bolt, and all systems of the manufactured new automatic rifle use a piston long-stroke gas-operated recoil automatic system to replace a piston long-stroke gas-operated automatic system corresponding to the AK47 rifle, and the other systems may use a mature design of the AK47 rifle. The high reliability of the AK47 rifle is maintained, and the recoil generated when bullets are fired is effectively overcome by means of the newly designed gas-operated recoil automatic system, thereby greatly improving the stability and accuracy of the rifle during continuous shooting, and thus achieving stealthy precise shooting. The automatic system is suitable for designing and manufacturing various medium-large-caliber automatic and semi-automatic assault rifles, sniper rifles, lightweight machine guns, anti-aircraft machine guns, anti-materiel rifles and anti-armor rifles with high reliability, high precision and high initial speed, and light weapons, such as grenade launchers and machine cannons of various calibers, and can form a complete medium-large-caliber automatic firearm system.
