JP Enterprises AR-15 Oversize .156 Anti-Walk Pins

JP Enterprises oversize anti-walk pins replace the hammer and trigger pins in an AR-15 lower. You get two .156 small pins and four button head screws, which hold the pins in place, look clean on the receiver and come out easily for service. Finish is black oxide.

These pins are oversized on purpose. The holes in your trigger and hammer may need to be reamed with a carbide reamer to fit. The lower receiver itself needs no modification.
