RISE Armament AR-15 5.56/.223 Low Mass Bolt Carrier Group - Black Nitride
The RISE Armament Low-Mass Bolt Carrier Group for the AR-15/M4 platform is precision made to MIL-SPEC using the highest quality materials and machining available. By reducing the mass of the BCG, felt recoil is diminished, allowing you to stay on target for more accurate shooting. The 8620 tool steel carrier and 9310 steel bolt have been treated with a black nitride finish for superior corrosion resistance and long service life. Each BCG is individually inspected to ensure only the highest quality components make it into your rifle build.
