Well made and looks very good - WMD Guns AR-15/M16/M4 Full Auto Bolt Carrier Group (BCG) - NiB-X Nickel Boron Polished

I can’t completely review this bolt carrier group because I haven’t shot the gun that it’s in. Just by observation, the BCG is very nicely made and looks like a very high quality product. It headspace’s perfectly. It’s very slick, moving in the upper receiver very easily without any oil on it. The BCG is reasonably priced and I feel that it will work well for years to come.
