Hi, I was given an upper and Im not sure of the make.

It looks like a heavy wall billet
no forward assist
a 9 mm deflector and door
Large front pin hole
no markings, other than an "A" on the back side of the rear pin hole.

Any leads appreciated.

Well it's not a dedicated 9mm since there's a gas tube hole in it.

Could be RR, or CMMG with that 1/2 ejection port / brass deflector. Do you absolutely need to know who is came from?

Was the enlarged front take down looks like it was made for an old COLT lower when they did their little stinking to make sure only their uppers worked.
