CMC Single Stage AR15 Trigger

91501 / 91503

The CMC Single Stage AR15 trigger features a non-adjustable trigger bow, and a crisp glass-like break.  CMC Single Stage AR15 Triggers have almost no take-up and extremely short reset to make follow up shots fast and easy. The hammer is lightened and uses a high-power Rocket Wire spring that ensures reliability with commercial and surplus ammunition. The high-power spring also results in minimal lock time, which is the time it takes for the hammer to fall and strike the primer, resulting in much more accurate shots. CMC Triggers have invested in a new production and tooling setup that incorporates advanced techniques helping to reduce manufacture time and cost while still providing you with an affordable, high quality and reliable trigger.

Available in flat or curved trigger bows, and pull weights ranging from 3.5lbs to 6.5lbs
