Ar-15/M16 Curved 2-Stage Trigger

A CMC Triggers AR-15/M16 curved 2-stage trigger transforms your rifle's trigger control from mushy factory stock to match-grade performance. This drop-in replacement was engineered by competition shooter Chip McCormick to deliver the consistency of a fine trigger without requiring hand-fitting or guesswork. The curved trigger shoe provides a traditional finger placement for shooters who prefer the classic feel, making it a solid choice whether you're running precision drills at the range or working through a hunting season.

The 2-stage design lets you dial in exactly the trigger feel your shooting demands. Factory pre-set with multiple first-stage and second-stage pull weight combinations, you can select the setup that matches your discipline—whether that's accuracy-focused work, defensive training, or competitive shooting. The staged break keeps your shot surprise-free and helps you isolate your trigger control from the rest of your fundamentals.

CMC built this trigger around a robust steel housing that keeps every internal component in alignment for straightforward installation and zero wobble. Precision-ground sear and hammer surfaces deliver a clean, crisp break while maintaining reliable function across thousands of rounds. Threaded sleeves on the pivot points run smooth and reduce friction wear. Oversized center pins replace standard pins to minimize play, and Chicago-type screws lock everything down without creep. The factory has already dialed in minimal take-up and over-travel, so you install it and shoot.

Frequently Asked Questions

What's the difference between a 2-stage and single-stage trigger?

A 2-stage trigger has two distinct pull phases: the first stage (or "set") takes up slack with moderate pressure, and the second stage (or "release") applies the final pressure to break the shot. This staged design can help you isolate trigger control and is favored for precision shooting. CMC also offers single-stage models for different preferences.

Will this trigger fit my AR-15?

This trigger is designed for AR-15 and M16 pattern rifles. It's a drop-in replacement, meaning it should install into your lower receiver without additional fitting, but always verify compatibility with your specific platform before purchase.

Do I need to adjust this trigger after installation?

No. CMC pre-sets each trigger at the factory with adjusted take-up and over-travel, so it's ready to shoot once installed. However, you can choose from factory pre-set pull weight combinations before purchase to match your shooting style.

What makes the curved trigger shoe different from a flat one?

The curved shoe provides a traditional trigger feel and finger placement. CMC also offers a flat trigger shoe option, which some target shooters prefer for a different finger-to-trigger geometry—it's really about personal preference and shooting discipline.
