CMMG Zeroed Anti-Walk Trigger Pins Features The CMMG Zeroed Anti-Walk Trigger Pins address a known weakness in mil-spec style trigger pins which can gradually walk out of one side of the receiver during firing particularly with cassette style drop-in trigger packs. Each pin is secured by Torx T8 screws rather than relying on friction fit alone locking the pin firmly in place so it cannot migrate under recoil. Constructed from steel these pins are built to hold up to repeated cycling without wearing or deforming at the pin holes. Fitting .154 inch diameter pin AR receivers they are sized to the most common AR-15 and AR-10 pattern lower receivers on the market. A drop-in trigger is one of the easiest upgrades to take an AR platform rifle from merely functional to genuinely exceptional and a secure non-walking pin set ensures that upgrade performs reliably over the long term. The kit includes two trigger pins and four Torx T8 screws supplying everything needed for a complete installation without sourcing additional hardware. This upgrade is especially valuable for shooters running aftermarket cassette style trigger groups which are more prone to pin walk than a standard mil-spec trigger. For AR-15 and AR-10 owners looking to secure their trigger pins permanently the CMMG Zeroed Anti-Walk Trigger Pins are a simple effective solution.
