This invention concerns a unique firearm trigger, safety and stock attachment mechanism and to an embodiment in a semi-automatic blowback rifle where the receiver is mounted in the buttstock, a style commonly referred to as a "bullpup". The trigger is a dual electrical and mechanical design with one trigger lever and a control timer. The safety is forward mounted and blocks the sear. The stock mounting prevents bending moments in the stock to be transmitted to the barrel/receiver assembly. The bull-pup rifle embodiment itself has several unique features including a cheekpiece removable from the stock.
An adapter for converting a handgun into a rifle or carbine. The adapter includes an elongated member having a stock and a pair of sidewalls forming a cavity. A pair of guide rails is positioned on an inner edge of the cavity, and a locking bar is mounted within the sidewalls and extends across the cavity. The locking bar is selectively positionable between a locked position and an unlocked position. A handgun mounts into the adapter by aligning channels on the outer edge of the handgun into the guide rails. The handgun is slid along the guide rails and into the locking mechanism for attachment.
