When you’re done messing with inferior equipment and you’ll take the time to choose the best components to upgrade your rifle or build one from the ground up. If a full mass bolt carrier group is one of the components you’re after, the Radian Weapons (formerly AXTS Weapons System) Black Nitride Full Mass Bolt Carrier Group should be at the top of your list. They’ve spared nothing here, and the result is a bolt carrier group of such fine quality you’ll be hard pressed to do better at any price.
Radian precision machined the body of this full mass bolt carrier group from 8620 case hardened steel. The bolt itself is 9310 case hardened steel. It’s been shot peened, high pressure tested and magnetic particle tested and then given a slick black nitride coating. The ultra-smooth black nitride finish features a lubricity all its own for long lasting smooth operation without additional lubricants to attract dirt and mess up the works. Radian even took the time to precision-grind the bolt lugs on CNC equipment after they were heat treated. As a result, there’s no distortion to adversely affect accuracy. The result is a bolt carrier group that will outlast the competition, cycle after cycle.
Radian not only machines their full mass bolt carrier group from the best quality American made steel, they per-installed a 4130 steel gas key and take the time to properly stake it so you don’t have to worry about failure or redoing the job yourself. Radian only wants to put the best quality products into every shooter’s hand. Whether you’re in special ops, or you just want to build the best weapon system for your own defense, Radian makes quality products that will serve you well in the real world.
