CMC Triggers Drop-In Two Stage Trigger Group for AR-15/LR-308

The CMC Triggers Drop-In Two Stage Trigger Group for AR-15/LR-308 is a factory-adjusted, match-grade trigger assembly that installs without fitting or gunsmithing. Built on the proven drop-in trigger module design, this two-stage trigger replaces your rifle's factory unit with a smooth pull, crisp break, and short reset—ideal for competition shooters, precision rifle enthusiasts, and hunters who demand consistent trigger control. Unlike aftermarket triggers that require hand-fitting and adjustment, CMC's design comes pre-set from the factory, so you get a refined shooting experience right out of the box.

The assembly uses a robust steel housing to keep all internal components properly aligned during installation and firing. Precision-ground sear and hammer engagement surfaces deliver a clean, predictable break while maintaining reliable function across thousands of rounds. Threaded sleeves on the hammer and trigger pivot points eliminate friction and provide smooth, consistent movement. Two oversized center pins replace the standard pins to prevent trigger wobble and reduce wear, while Chicago-type screws keep everything locked in place without pin walk.

CMC offers this two-stage trigger in multiple pull-weight combinations, letting you dial in the first (set) and second (release) stage weights that suit your shooting style. Choose between a traditional curved trigger shoe for classic ergonomics or a flat shoe preferred by many target shooters for a different trigger-to-finger feel. Minimal take-up and over-travel ensure fast, predictable performance on the range or in the field.
