So as the title says it’s a Colt Canada/Diemaco Anchor Harvey foraged marked M4 upper receiver.
The BCG is colt marked and so is the 14 1/2” barrel.
It also comes with the knights armament ras m4 rail and VG/Rail covering accessory bag and matech rear sight.
It’s been gaged (pictures of it being gaged) and found to be A+ condition mechanically sound
and there is very little wear marks on this complete upper receiver
