Abstract
An automatic projectile firing weapon and a related method for absorbing the recoil force of an automatic projectile firing weapon are disclosed. The weapon includes a barrel assembly that is slidably mounted in a receiver, biased by an operating spring, and engageable with a main sear. A gas operated bolt assembly is slidably mounted within the barrel assembly and is driven by a bolt spring. A trigger is provided to release the main sear and allow the operating spring to move the barrel assembly forwardly in the receiver. There is further provided a buffer connected between the receiver and the barrel assembly to dampen the velocity of the barrel assembly to ensure the barrel assembly is moving at a predetermined maximum velocity when a round is fired at a predetermined firing position. The recoil energy from the fired round is absorbed mainly by the forward motion of the barrel assembly and in part by the operating spring and buffer. In this manner, the peak recoil load to the receiver is minimized and the weapon operates at its actual firing rate from the first shot.
