This complete Trigger Assembly is CNC machined from aircraft aluminum and equipped with precision EDM parts. It features an internal pre-travel adjustment and a hammer that is precision ground from 440C stainless steel and hardened to 58 RC. The sear and disconnector are made of A2 hardened tool steel with tolerances of +/- .0002", complete with custom tuned springs. The trigger is black anodized, equipped with an overtravel adjustment screw and is reset internally to eliminate any dragging or inconsistencies caused by a conventional trigger plunger. An automatic bolt release and an extended magazine release are also included. Trigger pull is pre-set to 2 to 2-1/2 lbs. Due to the oversized safety used, it may be necessary for some stocks to be modified slightly to accommodate this part.
