I got this in on trade.
It came off of a 10.5inch upper assembly (machine gun)
It is just the upper receiver, with door and forward assist.
This DOES NOT come with the barrel, bolt, charging handle, bolt carrier, or any other parts.
It is just the assembled upper.
I am currently awaiting tools from bushmaster so I can swap in my A4 upper.
I am asking $80 shipped
EDITED-> this does not have a shell deflector and it does not have ANY marks to determine who made it.
