CMC Triggers Anti-Walk Pin Set Small Pins (Model 91401) eliminates a common frustration encountered by AR-15 and AR-10 builders: trigger and hammer pin drift during operation. The CMC Anti-Walk Pin Set provides positive retention of hammer and trigger pins, with cap screws that limit pin movement and prevent walkout. Made in the U.S.A. from steel, this set is designed to keep your trigger assembly functioning reliably through extended shooting sessions without the risk of pin failure.
The kit includes two steel pins, four screws, two wrenches, and installation instructions, with pin dimensions of 0.154″ diameter and 0.885″ length (small pin configuration). The kit includes two wrenches for easy installation and is compatible with MIL-SPEC lower receivers. This kit is compatible with CMC triggers and all small pin type AR-15 lower receivers. Installation requires no gunsmithing knowledge, and comes backed by CMC Triggers’ 100% Manufacturers Lifetime Warranty.
CMC Anti-Walk Pins are precision machined and held in place with retaining screws, providing an affordable safeguard against downtime and mechanical failures at the range or in the field. For builders and shooters who demand reliability without complications, this accessory is an essential investment in trigger assembly performance.
