imschur Posted March 4, 2012 Report Share Posted March 4, 2012 For my 300 Blackout build I decided to skip the Young MFG bcg's I normally purchase and give this Wilson Combat NP3 Coated Bolt Carrier Group a shot.This is my first NP3 coated part. Pretty slick stuff. The BCG appears to be machined pretty clean. Quote Link to comment Share on other sites More sharing options...
