AR15/10 PCC Single Stage Trigger – Curved
Due to the rise in popularity of Pistol Caliber Carbine (PCC) rifles and after careful research and development, CMC Trigger launched the CMC 9mm PCC Drop-in Trigger. The trigger’s hammer dimensions have been modified to work with all the various manufacturer bolt carriers designed for the 9mm platform. The CMC PCC trigger features a non-adjustable 3.5lb pull that breaks like glass.
CMC Triggers is the original manufacturer of the Drop-in Trigger Group for the AR-15/10 rifle since 2003. CMCs critical sear engagement surfaces have a proprietary machining process that renders superior surface finish and dimensional control. As compared to their competition, the techniques used to establish a 1-2 RMS surface finish as opposed to EDMing which leaves a pitty 32 RMS, compared to a mirror which is 0 RMS.

WHAT IS A SINGLE STAGE TRIGGER? – A single stage trigger requires one range of motion to pull the trigger in order to release the hammer. The benefit of a single stage trigger is that it’s simple. Most shooters agree that a single stage trigger is crisper in the break of the trigger because you don’t feel the initial resistance of the first stage. A majority of shooters prefer the single stage triggers for most applications.
CMC CURVED TRIGGER BOW – For the shooter who wants a traditional feel. The Classic Curved Trigger has an exceptionally smooth feel and ultra-clean break. With excellent lock time and lighting fast positive reset, the CMC Curved Trigger is unsurpassed by any other fire control group.
CMC FLAT TRIGGER BOW – Ultimate for feel and break. With the Shooters finger coming to rest naturally on the shoe, every pull is the same as the one before it. CMC’s patented Signature Flat Trigger Bow renders a linear feel unsurpassed by any other trigger bow shape.
CMC COMBAT CURVED TRIGGER (CCT™) BOW – The innovative design combines the comfort of the classic curve with CMC’s signature flat trigger indexing into one dynamic trigger bow for the modern warfighter. The CMC CCT™ has an exceptionally smooth feel, ultra-clean break, and an exceptional lock time and lightning-fast reset.
WHAT PIN SIZE SHOULD YOU USE?
LARGE PIN (.172 Ø) – Colt is the only AR brand to produce both small and large diameter pins in their triggers. Colt AR-15 rifles produced between 1991 and late 2009 commonly take a LARGE PIN.
SMALL PIN (.154 Ø) – If your AR rifle is NOT a Colt or your Colt was produced before 1991 or after 2009 it will take a SMALL PIN.
M&P 15-22 COMPOSITE PIN – The Smith & Wesson® M&P® 15-22 or any wider than standard receiver will use a SMALL PIN diameter but requires a longer pin length and will take an M&P 15-22 COMPOSITE PIN.
CMC Triggers offer all versions of their Drop-in AR Trigger in SMALL PIN, LARGE PIN, and M&P 15-22 COMPOSITE PIN. If you are still unsure of the pin diameter needed for your rifle you can take a measurement by pressing a pin far enough out of the receiver to measure its diameter, .172 Ø for LARGE and 154 Ø for SMALL.
