ABSTRACT:
The present invention relates to a firearm, generally of the automatic or semi-automatic type, having a reciprocating breech block normally biased into closed position by a primary recoil absorption system including a spring, the improvement comprising providing a secondary spring-biased recoil absorption system cooperating with the primary one during a portion of the retraction stroke of the block to slow down the movement of the latter before becoming inactive while the primary system slows the block to a stop and reverses its direction and then becoming active to once again cooperate with the primary system during a portion of the return stroke of the block to speed up its return to its original position. The invention also encompasses the improved method for controlling the movement of the breech block in the aforementioned type of weapon during its firing cycle wherein such movement during its initial and final stages is supplemented and abetted by a secondary spring-biased recoil absorption system cooperating with the primary one while, at the same time, leaving the primary system solely responsible during the remainder of the cycle to stop the block and reverse its action.
