<p>A semi-automatic, two-shot, gas-operated shotgun having a side-loading port, lower barrel configuration with bottom shell ejection. Gas exit ports (23) are spaced around the barrel (21) and operate a piston (29) which actuates a connecting rod assembly rearwardly. The rearward movement of the connecting rod assembly will comprise a recoil spring (42) and cycle the next shell into the chamber from a shell space (45) in the carrier (46) above the breech (24). The bolt assembly has upper and lower bolt members. Locking lugs on the opposite sides of the lower bolt are released by rearward movement of the upper bolt member. Reciprocal guide pins are located in the lower bolt member and are retracted into the face of the lower bolt to allow a spent shell to be ejected through the ejection port. The impact of the lower bolt member at the rear of the receiver (170) will drive the pins forwardly to direct a new shell into the breech (24). The modular trigger assembly has a hammer (31) which is rotated rearwardly by the lower bolt and which returns to a 'short lock time' position held ready to fire by a sear (35).</p> |
