DIY True North Arms TNA Bolt Carrier Group (Phosphate)
This is ideal for those of you who want to save a couple bucks through building your own BCG. I was busting balls looking for some cost effective BCG for you guys and made a deal with CNA to get some of their BCG that are un-assembled at a decent discount because the labour is costly to assemble, stake, and permatex a BCG.
Comes with CNA's M16 cut extreme duty-ready complete bolt and carrier assembly with firing pin.
Available with a 5.56x45 bolt
- Bolt assembly (complete already built)
- Note these gas keys and bolt carriers use the USA standard #8 screws (the kit comes with all the matching hardware)
