This bolt is simply fantastic. It's nice to see someone actually trying to improve the heart of the AR platform, the BCG. I paired my new bolt with a Phase 5 EN bolt carrier and also installed a POF roller cam pin. Let me tell you that it simply glides back and forth in the carrier. I don't think I'll ever go with any other finish besides the NP3+ finish..it's so slick.. I wish I would have just gotten the BBC to begin with. Oh well there's always Christmas.
