CMC Triggers 91503 Single Stage Flat Trigger For AR15 Rifle. CMC Single-Stage Flat Trigger Bow. CMC's single-stage trigger group is a completely self-contained, 100% drop-in, fire control group upgrade for the AR-15 and AR-10 family of rifles. Trigger pull is factory pre-set and is not user-adjustable. It has an ultra-crisp 3.5 lb trigger weight with no feel of creep prior to hammer release.
Trigger has a glass-smooth break with no feel of grittiness. Trigger components are fabricated from 8620 alloy steel and S7 tool steel, machined to exacting tolerances and finished for the longest service life possible. Minimal lock-time is designed into the assembly using controlled hammer weight and balance and activated using a rocket wire hammer spring. This assures repeatable function, with either commercial or military grade ammunition. Positive trigger reset allows a quick follow up shot on target. Trigger is easy to install following the included instructions.
CMC's innovative, self-contained, and easy-to-install AR-15 trigger groups have been completely re-tooled to maximize production capacities, incorporate new design enhancements and reduce cost. CMC's AR-15 trigger groups have always yielded exceptional trigger pull dynamics. CMC is confident the new production tooling and setup, incorporating the most advanced methods available, will not only yield the highest quality, but will also keep the supply lines full so every AR-15 shooter who places the highest demands on quality, function and reliability, will no longer have extensive lead times for obtaining these innovative trigger groups. And thanks to our multi-patented designs, a fine match grade trigger pull is now an extremely simple upgrade to implement. Install the fully self-contained, ready-to-go trigger group, safety check, and it's done.
