CMC Triggers 91501 Drop-In Single-Stage Curved Trigger, 3-3.50 lbs Draw Weight, Black/Silver Finish for AR-15/AR-10

The CMC Triggers 91501 drop-in single-stage curved trigger is a match-grade AR-15/AR-10 trigger upgrade designed to replace the mushy, heavy pulls found in factory receivers. Built by competition shooter Chip McCormick, this self-contained trigger module installs without fitting or adjusting multiple components—just drop it into your lower and you're done. You get a crisp, clean break with a factory-tuned pull weight between 3 and 3.5 pounds, tuned for precision shooting whether you're running a long-range rifle, competition build, or hunting platform.

The rigid steel housing and precision-ground sear and hammer surfaces deliver that snappy, predictable release serious shooters demand. CMC engineered every detail to minimize take-up and over-travel, so you feel exactly where the trigger breaks. Threaded pivot sleeves keep the hammer and trigger moving smooth and fast, while slightly oversized center pins and Chicago-style screws eliminate flex and pin walk—a common source of creep in budget triggers. The curved trigger shoe gives you that traditional, comfortable profile many AR shooters prefer, and the black/silver finish fits most build aesthetics.

This is the kind of upgrade that transforms how your AR feels and shoots without requiring a gunsmith or a parts pile on the workbench. Whether you're building a precision rifle or improving an existing one, a quality single-stage trigger is one of the highest-ROI upgrades you can make.

Frequently Asked Questions

Will this trigger fit my AR-15 lower receiver?

The CMC 91501 is designed as a drop-in module for standard AR-15 and AR-10 platforms. Because it's a self-contained assembly, it should install without modification; however, if you have questions about your specific lower, check with the manufacturer or contact us.

Is this a competition trigger or a hunting trigger?

The CMC single-stage was originally designed by competition shooter Chip McCormick and is popular in precision and competition builds. That said, a crisp, clean pull and light weight benefit any shooter—hunters, tactical shooters, and target shooters all appreciate the reliability and feel. It's a versatile upgrade for any AR platform.

What's the difference between the curved and flat trigger shoe?

This model features the curved trigger shoe, which provides a traditional, comfortable profile. CMC also offers a flat-shoe version that some shooters prefer for a different feel and a more skeletal appearance. Both are single-stage triggers; the choice is mostly personal preference and aesthetics.

Do I need a gunsmith to install this?

No. This is a drop-in trigger module that replaces your factory trigger assembly. Installation requires removing your factory trigger pin and installing this assembly—no fitting, adjusting, or special tools required. If you're comfortable working on your AR, you can do this yourself.
