Abstract:
An automatic projectile firing weapon, the weapon comprising:a receiver having a main sear and a trackway; a barrel assembly slidably mounted in said trackway and moveable between a rearward position and a forward position, said barrel assembly being engageable with said main sear at the rearward position and having a firing position between the rearward position and the forward position; an operating spring connected between said receiver and said barrel assembly, said operating spring biasing said barrel assembly toward the forward position; a retracting device operable to move said barrel assembly rearwardly into engagement with said main sear, thereby compressing said operating spring; a trigger for releasing said main sear, thereby allowing said operating spring to move said barrel assembly forwardly; and a buffer connected between said receiver and said barrel assembly to dampen the forward velocity of said barrel assembly such that said barrel assembly is moving at a predetermined maximum velocity when the barrel assembly reaches the firing position, whereby the recoil energy from firing said round is absorbed in part by the forward motion of said barrel assembly and in part by said operating spring.
