This was sold to me as Bushmaster but I don't have any way to confirm it. I don't have any reason to not believe the seller but feel I should put that out there.
This is a Low milage bolt/carrier assy. Ready to put into an upper and shoot.
I put 30 rounds through it. I would guestimate the round count around 100 rounds.
