The RISE Armament RA-1010 Low-Mass Bolt Carrier Group for 223/5.56 is engineered to reduce reciprocating mass during the firing cycle, minimizing recoil while maintaining full power in a lightweight design. The complete assembly weighs 8.9 ounces and features a black nitride finish that enhances strength and reduces friction for improved performance.
The bolt is 9310 MPI tested, while the carrier is constructed from 8620 tool steel, heat treated and case hardened. The gas key is tool steel with grade 8 hardened fasteners, properly staked. The cam pin is 4140 steel, and the extractor is tool steel, shot peened. Each unit is precision manufactured, individually inspected, and individually MPI tested for reliability.
This BCG is compatible with lighter buffers to enable faster follow-up shots and weighs only 8.9 oz. The RA-1010 is also available in nickel boron coating, which reduces friction, improves overall performance, and makes cleaning easier. Built for more accurate shooting, this low-mass BCG delivers lighter, faster, and more manageable rifle performance.
