CNA Bolt Assembly (.223/5.56) (Nickel Teflon)

  • 9447


This is a complete bolt assembly with a .223/5.56 face, from Canadian National Arms. It includes the Ejector, Extractor and Gas Rings. This is a heavy-duty bolt designed for use in an M16 but works great in an AR-15. The difference is this one is a sexy silver colour due to the Nickel Teflon coating.

Nickel Teflon has a number of advantages over common phospate or nitride coatings. The low friction means less wear, so it lasts longer. And you can run it without lube, which has the side benefit that it needs less frequent cleanings because there is no oil to get baked and foul things up.
