  • Mil-Spec trigger pins may work fine, for a while. When you squeeze off enough rounds they won’t. They’re a lot of companies making lower receivers and just a difference of a thousandth of an inch makes a lot of difference. A set of anti-walk AR trigger pins will make a lot of difference too. That difference could just be a day at the range, or it could mean your life. CMC gives you a low-cost insurance policy in a set of anti-walk AR trigger pins. Bullets, flash, and sound are all that’s supposed to come out of your AR. CMC Anti-Walk Pins are precision machined and held in place with retaining screws so you never have to worry about them coming out of place. CMC gives the same attention to detail to a seemingly insignificant part as a set of anti-walk AR trigger pins as any other part they manufacture. You need that kind of care when deciding on such a critical part to pair with your weapon.

CMC Triggers innovative, self-contained, and easy-to-install AR-15 Trigger Groups, have been completely re-tooled to maximize production capacities, incorporate new design enhancements and reduce cost to the customer. CMC Triggers AR-15 Drop-in Trigger Groups have always yielded exceptional trigger pull dynamics for our hundreds of thousands of satisfied customers.

CMC's critical sear engagement surfaces have a propriety machining process that renders superior surface finish and dimensional control. As compared to our competition, the techniques we use establish a 1-2 RMS surface finish as opposed to EDMing which leaves a pitty 32 RMS at best. Compared to a mirror which is 0 RMS, this is what sets the CMC Trigger apart from it competition. CMC Triggers sear engagement overlap is up to 6-8 times greater than our competitors. This provides a much safer trigger and enhances reliability.
