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

RISE Armament’s RA-1010 Low Mass Bolt Carrier Group is the ultimate was to make your AR15 lighter, faster, and more manageable. Weighing in at less that 8.9 ounces, the RA-1010 reduces the reciprocating mass during the firing cycle. This in turn cuts down on recoil and helps you stay on target. Like all of RISE Armament’s products, the RA-1010 Low Mass Bolt Carrier Group’s production quality is nothing short of exceptional. Each component is precision manufactured and individually inspected to ensure high-level performance, and a nickel boron coating reduces friction, improves overall performance, and makes it easier to clean.
