ABSTRACT:
A proven sporting type shotgun with the stock removed therefrom converted to a military combat type weapon by addition of a retrofit assembly which includes a retrofit housing containing the trigger of the basic sporting shotgun and at least a portion of the shotgun receiver. The trigger of the shotgun is operated by an elongated trigger connector assembly operably connected to a primary trigger supported on the retrofit housing forward of the shotgun trigger. The gun safety mechanism includes a blocking cam biased to a blocking position wherein it engages an abutment surface on the trigger guard of the shotgun to prevent movement of the shotgun trigger to its firing position. A cam roller carried by the trigger connector assembly cammingly engages the blocking cam during inital rearward movement of the primary trigger to move the blocking cam to a releasing position relative to the shotgun trigger. Further rearward movement of the primary trigger causes the roller cam to move the shotgun trigger to its firing position and thereby discharge the gun. The retrofit assembly further includes a grip safety and a crossbolt safety, each for blocking the primary trigger in safe position to prevent rearward movement of the primary trigger.
