Our 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 its 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.
