Great functioning bcg - Radian Weapons Enhanced Black Nitride Bolt Carrier Group (BCG)

I have this Radian enhanced BCG and I own a Midwest Industries enhanced BCG and their both identical and made by the same manufacturer. Only difference is the logos and the Midwest Industries is about $40-$50 cheaper but the same. No issues after 1800rnds. I replaced the cam pins with Lantacs Domed cam pin and I replaced the one bolt with JP Rifles enhanced bolt. Nitride is holding up pretty well with some slight wear on the rails. One bcg had some pretty weak gas key staking and the other was good.
