Rise Armament RA-1010 Low-Mass Bolt Carrier Group .223/5.56 NATO Black Nitride

Description

Product Overview

The Rise Armament RA-1010 low-mass bolt carrier group is built for the AR-15/M4 platform in .223/5.56mm NATO. It uses a case hardened 8620 tool steel carrier and a 9310 steel bolt, both finished in black nitride for improved corrosion resistance and long service life. The result is a lighter-feeling reciprocating assembly designed to help reduce felt recoil and stay on target, including use with lighter buffers.
