I cant make it expand. I  cannot see that logo good enough.

Based on the model number, it appears to be a 17 Design and Manufacturing

Maybe it’s an AR-549 upper.  

[Johnny Rotten]

It's a AK47 forged upper

I was asking about the upper. I know what the lower is.  

[bubbadavis]

Duh! Evidently reading and comprehending is hard for me…

I have an upper similar to that from Daytona Tactical. No markings and the hand guard is the same design but it is black.

@JeffsSig, pretty sure that is a Troy MRF rail

It is the kind you should send me for proper testing. Should not take but a few weeks, no wait, months. Be sure to send 2K rounds of ammo, that should be enough to do a good test. PM me for my address.

Best I can tell its an Aero.

[Erich]

Doh, you meant the upper receiver. I misread.

That is an Aero M4E1 threaded vs enhanced. they look better with their lower imo.
