Unmarked BCG: who made it?

[Seanxlu]

I just bought a black BCG from a fellow member... It looks like an M16 BCG, well built, never put in an upper, comes in a yellow nylon web sleeve, but completely unmarked - not a single letter or number.

Is there a way to find who made it? See images.

The previous owner says it was from one of the major manufacturers but not sure which one.

Somebody who sees a lot of bolt carriers from known sources might be able to make some educated guesses based on the shape of the stake marks on the gas key. But otherwise, it's not possible without some kind of marking. The important thing is that it's an auto carrier, with well staked screws. Is the bolt marked "MPI HP"?

Thanks.
I'll have to take bolt out to see it. When I get home...

I am betting that came out of New Frontier Armory out of Las Vegas. They didn't build them, they had them built somewhere to their specs and I have not been able to find out who actually bid them. Is it ceramic coated?

Well it looks like phosphates.
