is a brand new, never been fired, 20", no ban A2 Upper. It comes with the charging handle, elevation and windage-adjustable rear sight, and compensating flash hider which is threaded to the barrel. The receiver has a Colt-like dark gray finish, the barrel is marked, "P MP 5.56 NATO 1/7", and the front sight is marked, "D99 (R1) 1" and is mounted with taper pins. I mounted it briefly on my Olympic lower and the fit was very good but that is the only time it has been installed on a lower. ETA:
In response to some questions asked.
1. The barrel was designed as part of a conversion kit for the M16A1 and from what I can find, it was manufactured by either Capco, Inc. or DPMS. I am not 100% certain that it is chrome lined but I am inclined to think it is.
2. It has the government profile with the light contour under the handguard.
3. I do not have a bolt /carrier assembly to send with it. I'm sorry!
Asking price is $290 Shipped.
I will be happy to send more pictures if needed. Thanks for all your interest!
