RISE Armament RA-1010 Low-Mass .223/5.56 Bolt Carrier Group - Nickel Boron - RA-1010-NiB

Packing exceptional performance in a lightweight – but full-power package – RISE Armament designed the RA-1010 Low-Mass Bolt Carrier Group (BCG) to help you shoot more accurately. With a reduced reciprocating mass during the firing cycle, it lessens recoil and helps you stay on target. The complete BCG weighs in at just less than 8.9 ounces. Its nickel boron finish reduces friction, improves overall performance, and makes it easier to clean.
