CMMG 55AFF75 Lower Pins & Springs Kit AR-15 Black

The CMMG 55AFF75 is a replacement lower pins and springs kit for the AR-15 platform. Designed by CMMG as a complete service set, this kit provides all of the small wear-item hardware needed to refresh or rebuild an AR-pattern lower receiver.

The kit includes two trigger pins, three trigger springs, the bolt catch roll pin, the trigger guard roll pin, the bolt catch detent, two takedown pin springs, and two takedown pins - covering the core pins, detents, and springs used in a standard AR-15 lower assembly.

Built for the AR-15, M16, and M4 platform, the 55AFF75 is finished in black and is intended as a direct-fit replacement for armorers, gunsmiths, and home builders refreshing a worn lower or completing a stripped lower receiver build.
