The CMC Triggers Drop-In AR Trigger is a single-stage flat trigger built for shooters who demand match-grade performance without the hassle of a gunsmith visit. With a factory-preset 2.5lb pull, this fully self-contained trigger group drops into any MIL-SPEC AR-15 or AR-10 with zero user adjustment needed—just install it, run your safety check, and shoot. If you're competing at a serious level or simply refuse to compromise on trigger quality, CMC's proprietary machining and sear geometry give you the crisp, consistent break that separates a precision rifle from the rest of the rack.

What sets this trigger apart is the engineering underneath. CMC's sear engagement surfaces are machined to a 1–2 RMS finish—dramatically finer than the conventional EDM process—which translates to repeatable, glass-smooth performance shot after shot. The overlap between sear and hammer is 6–8 times greater than typical competition, delivering both safety and reliability you can count on with commercial or military-grade ammunition. The flat trigger bow is purpose-built for a natural finger position; every pull feels identical, which is exactly what a competitive shooter needs when precision matters.

Assembly is hand-done and hand-tested at CMC, so you're getting a trigger that's been quality-checked before it ships. The 8620 alloy steel and S7 tool steel construction is machined to ±.001" tolerances, and the minimal lock time design—achieved through controlled hammer weight and CMC's proprietary spring geometry—ensures fast, reliable ignition. Installation is straightforward; the trigger ships with a small anti-walk pin set (.154″ diameter) and fits standard MIL-SPEC platforms. If you've been running a mushy factory trigger or wrestling with compatibility headaches, this CMC drop-in eliminates both problems.
