closing of the chamber 16 is caused by retracting the hydraulic cylinder 74 enabling the slide to move forward along the track 79 thereby causing the closing of the chamber 16 and locking of the chamber to the breech 14 as the latch 88 re-engages the notch 90. The piston end 96 is not attached to the slide, at this time,hence,the breech is free to slide within the receiver 12 upon recoil of the gun without further movement of the cylinder 74
