CMC Triggers Anti-Walk Pin Set – Small Pins for AR-15/AR-10

Anti-walk pins prevent trigger and hammer pins from walking out of the lower receiver during firing, a common issue with aftermarket triggers or receivers with oversized pin holes. This CMC Triggers small pin set replaces standard .154" diameter trigger/hammer pins with captured pins that stay locked in place, eliminating pin migration and maintaining consistent trigger performance. Essential for shooters running drop-in trigger systems or experiencing loose pin fit.

Machined from hardened steel with a matte black finish. These are true drop-in pins—no drilling, tapping, or permanent modification to your receiver required. Simply drive out your existing pins and install these in their place. The side screws provide retention without damaging the receiver. Includes both trigger and hammer pins.
