DIY True North Arms TNA Bolt Carrier Group (Phosphate)

  • 15997

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)
  • Bolt carrier has the M16 cut
  • Made by a military contractor
  • Magnesium Phosphate finish
  • 8620 steel carrier
  • 9310 steel bolt

You get:

  • (1) Complete Bolt (extractor, ejector pre-installed)
  • (1) Stripped carrier
  • (1) Gas key
  • (2) Gas key screws
  • (1) Cam
  • (1) Firing pin
