ABSTRACT:
In an automatic shoulder arm designed as a gas operated weapon, especially an automatic rifle, the entire, fully operable weapon system, comprising the barrel, the bolt system, the gas operated action, the recoil spring arrangement, the cartridge feeding mechanism and a portion of the trigger mechanism, is slidably mounted in a receiver designed as a stock. During automatic fire, the weapon system is not returned to its initial position after every shot, but performs a recoil movement during a plurality of shots before it reaches a rear end position, which it maintains until the automatic fire is interrupted. The recoil movement can be utilized for controlling bursts of varying duration and cadence.
