CMC AR15/AR10 Single-Stage Trigger - Silver, Curved, 2.5 lbs Pull

A CMC AR15/AR10 single-stage trigger with a 2.5 lb pull weight transforms how your rifle breaks. Chip McCormick, a competition shooter, designed this drop-in module to replace the heavy, mushy factory trigger that ships on most commercial AR-15s—giving you a crisp, clean release that's truly match-grade without the hassle of fitting and adjusting individual components. The whole assembly slides into your lower receiver as a self-contained unit, so installation is fast and straightforward.

The magic is in the engineering. A rigid steel housing keeps all internal parts in perfect alignment, while factory-tuned sear and hammer engagement surfaces deliver that snappy, predictable break you want when the shot matters. CMC machines generous contact surfaces there, giving you a clean release while keeping the trigger reliable—no finicky two-stage surprises, just a straight, single-stage pull. Threaded sleeves replace standard pivot pins with oversized, precision-ground surfaces that glide smoothly with almost no friction. Two larger center pins and Chicago-style screws lock everything in place so your trigger stays tight through hundreds of rounds.

This version features the curved trigger shoe, which gives you the traditional ergonomic feel many shooters know and prefer. The silver finish matches polished AR internals and looks clean. CMC has already dialed in pull weight, take-up, and over-travel at the factory, so you're getting a pre-set, ready-to-run trigger—no gunsmithing required. Whether you're shooting precision rifle, 3-gun, or hunting, stepping up from a factory trigger makes an immediate difference in how your AR performs.

Frequently Asked Questions

Will this trigger fit my AR-15 lower receiver?

Yes. CMC's single-stage trigger is a drop-in module designed for standard AR-15 and AR-10 lower receivers. Installation requires no fitting or modification.

What's the difference between this curved trigger and a flat trigger?

This trigger has a curved trigger shoe, which offers traditional ergonomic control and feel. CMC also offers a skeletonized flat shoe option that provides a different shooting feel and a distinctive appearance—that's a separate listing.

Is the 2.5 lb pull weight adjustable?

No. The pull weight is factory-set to 2.5 lbs and not adjustable. CMC has pre-tuned this assembly for consistent performance out of the box.

What makes this trigger cleaner than a factory AR trigger?

CMC machines generous sear and hammer engagement surfaces and uses oversized, threaded pivot pins instead of standard components. These precision surfaces glide smoothly and deliver a crisp, predictable break without the creep and grittiness typical of factory triggers.
