CMC Triggers Anti-Walk Pin Set S&W M&P 15/AR-15 Polymer Lowers - Black

The CMC Triggers Anti-Walk Pin Set (Model 91403) solves one of the most common reliability headaches in AR-15 builds: trigger and hammer pins drifting out of a polymer or composite lower receiver during use. This small-pin kit locks both pins positively in place so the trigger group cannot walk sideways and bind up under hard recoil.

Engineered specifically for the Smith & Wesson M&P 15-22 and every other composite / polymer lower on the market, the set also fits all AR-15 and AR-10 rifles that use the smaller 0.154" pins. The kit ships fully self-contained with 2 posts, 4 screws, and 2 wrenches so installation and removal require no specialty tools.

Each pin is machined from steel with a black finish and measures 0.154" diameter by 0.885" length for a precise, drop-in fit. Positive retention of the hammer and trigger pins delivers improved reliability of the trigger assembly, and CMC Triggers backs the kit with a full manufacturer warranty. Made in the USA.
