CMC Single Stage Trigger

The CMC Triggers AR-15/AR-10 Single Stage 3.5 lb Flat Trigger represents one of the most popular drop-in trigger upgrades for AR-platform rifles. CMC, a Texas-based company, has built a reputation for innovative, self-contained trigger groups that offer exceptional feel without the complexity of adjustable triggers. The flat trigger bow design provides a linear feel unsurpassed by curved alternatives, allowing the shooter's finger to rest naturally on the shoe for consistent pulls shot after shot.

Constructed from 8620 alloy steel and S7 tool steel with machining tolerances of +/- .001", the CMC trigger delivers an ultra-crisp break with minimal lock time and a positive, short reset. The critical sear engagement surfaces utilize a proprietary machining process that produces superior surface finish and dimensional control. The trigger pull is factory pre-set and not user adjustable, eliminating the possibility of inadvertent changes during use. All CMC triggers are completely self-contained, making installation as simple as dropping the unit into the lower receiver and securing with the included pins.

Real-world users praise the CMC for its clean break with no creep and a short, snappy reset that facilitates rapid follow-up shots. The flat-faced design provides excellent control and a positive feel, with the hook providing an index point for consistent finger placement. While some users note the break isn't quite as glass-rod crisp as premium Geissele triggers, at the $130-170 price point, the CMC represents excellent value. The trigger includes anti-walk pinset screws (do not exceed 12 in-lb torque) and has proven totally reliable in both suppressed and unsuppressed configurations.
