Will this function with a 762x39 bolt? Expert Answer

Does this come with firing pin and all Expert Answer

No, it is the carrier and gas key only. It is not a complete BCG.

Helpful Negative Review Worse nickle boron coating I've ever seen by JET, Verified Owner, November 29, 2022
The title pretty much covers the review. I've never dealt with this company before and I doubt I ever will after receiving this bolt carrier. It was not even a smooth coating/surface, very rough. There were also a few metal burrs.
