The Radian Enhanced Bolt Carrier Group Blem for AR15 in .223/5.56 with Black Nitride finish offers the same exceptional performance as the standard version, but at a reduced price due to minor cosmetic imperfections. This BCG features a case-hardened 9310 steel bolt and 8620 steel carrier, both treated with a self-lubricating black nitride finish. Engineered to minimize carrier tilt and reduce friction, this blemished BCG maintains the same high standards of performance and reliability as its non-blemished counterpart.
