Rise Armament RA-1010 Low-Mass Bolt Carrier Group - Nickel Boron (RA-1010-NIB)
Maximize speed and accuracy in your AR-15 with the Rise Armament RA-1010 Low-Mass Bolt Carrier Group in Nickel Boron finish. This lightweight, full-power BCG reduces reciprocating mass during the firing cycle, cutting recoil and enabling faster follow-up shots—ideal for competition builds, suppressed setups, lightweight rifles, or high-performance tactical guns where every fraction of a second counts and reliability is non-negotiable.
Weighing in at just under 8.9 ounces, it's precision-engineered with a 9310 MPI-tested bolt and 8620 tool steel carrier, properly staked gas key with grade 8 fasteners, and a Nickel Boron coating that slashes friction, boosts lubricity, enhances durability, and makes cleaning a breeze. Compatible with lighter buffers for even quicker cycling, this BCG delivers exceptional reliability in 5.56 NATO, .223 Rem, or .300 BLK platforms.
