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. <
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 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.
