RISE Armament AR-15 Nickel Boron Low-Mass 5.56 Bolt Carrier Group

The RISE Armament® AR-15 Nickel Boron Low-Mass 5.56 Bolt Carrier Group (BCG) is perfect for those who want a lighter, faster, and more manageable rifle for improved accuracy and superior precision. This BCG boasts a reduced reciprocating mass that lessens your rifle’s recoil for faster follow-up shots at the range or in the field. Plus, this BCG is compatible with lighter buffers to allow you to truly dial in your rifle and maximize it for speed. What’s more, the gas key boasts tool steel construction with grade 8 hardened fasteners that are staked properly to help ensure proper cycling every time you pull the trigger. Further, the 4140 steel cam pin and shot peened tool steel extractor round out this BCG and ensure safe and proper function when shooting your favorite rifle. This BCG features a heat treated and case hardened 8620 tool steel construction carrier with a corrosion-resistant and easy-to-clean nickel boron finish for superior strength and smooth and reliable function while the 9310 MPI tested bolt works with the extractor to help ensures each round is properly seated into place. Backed by a lifetime warranty from RISE Armament. Made in USA.
