ABSTRACT:
The sub machine gun fires single shots in semi automatic fashion, and also fires fully automatically, with the firing mode being manually selectable. The firing mode selection also includes a safe setting, and there is a grip safety which renders the gun inoperative unless the pistol grip is squeezed. The safeties are configured and balanced so that the gun will not fire if dropped. There is one manually operable latch that allows complete take down of the action. When the receiver cover is lifted with the bolt cocked, the bolt will not accidentally move forward to fire the gun. The slide actuator holds the receiver cover in its open position. The barrel is latched in place by a latch pin that cannot unintentionally be removed from the gun and misplaced. The barrel latch pin can be partially withdrawn to allow removal of the barrel from the receiver. The sear, through interaction of the grip safety, also prevents the bolt, if in the fired position, from reaching the cocked position if the gun is accidentally dropped. This prevents the gun from accidentally being fired.
