CMC AR15 / AR10 Anti-Walk Pin Set Small Pin

Anti-walk pin set for securing trigger and hammer pins in AR lowers

The CMC AR15 / AR10 Anti-Walk Pin Set Small Pin is designed to prevent lateral movement of the trigger and hammer pins inside the AR lower receiver. The screw-retained design keeps the pins securely in place, even under sustained use.

This set is intended for AR platforms using the small pin specification and supports consistent operation of the trigger system. Precision-machined pins help reduce receiver wear while maintaining a stable, precise fit.
