Seekins Precision NX15 5.56 NATO Bolt Carrier Group

Smooth cycling, reliable extraction, and proper feeding are the hall marks of a quality bolt carrier group such as the Seekins Precision NX15. Built to MIL-SPEC dimensions to ensure a drop-in fit on any AR-15 or M16 rifle or pistol, the NX15 was then lightened slightly to reduce cyclic mass and improve lock time and felt recoil. Each NX15 bolt carrier group is equipped with a magnetic particle inspected 9310 super steel bolt assembly for an extended service life, and treated finished with Seekins Precision's Element Surface Treatment for a low-friction, minimal maintenance part you can rely on.
