CMMG 38AFF31 MK3 HD Pivot and Takedown Pin Set .308 Win Black

The CMMG 38AFF31 MK3 HD Pivot and Takedown Pin Set is a drop-in upgrade built specifically for CMMG MK3 .308 Win / 7.62x51mm NATO LR-308-pattern lower receivers. Made of metal with a black finish, these slightly oversized HD (Heavy Duty) pins take up the slack between the upper and lower to reduce wobble and receiver slop, delivering a noticeably tighter, more solid feel at the shoulder.

Both pins feature an extended, dimpled tip that accepts the nose of a standard rifle cartridge or any common punch, giving you fast, hassle-free takedown and pivot-pin removal without scratching the receiver finish. The set includes one pivot pin and one takedown pin, purpose-built for the CMMG MK3 lower and intended for .308 Win / 7.62x51mm NATO LR-308-pattern rifles - not for use on standard AR-15 / M16 lowers.
