CMC 91504 Drop-In Two-Stage Flat Trigger 1-3 lb

The CMC Triggers 91504 is a self-contained drop-in two-stage flat trigger designed for AR-15 platforms. It delivers a defined first-stage take-up and a precise second-stage break with a specified pull weight range of 1–3 lb. The assembly uses full-strength music wire springs and is contained in a high-grade 410 stainless steel housing for durable service life. Installation is straightforward: the one-piece assembly installs with the supplied pins and is intended for mil-spec receivers with small pins; it does not fit Colt AR-15 models with a sear block.
