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.
