I have for sale a PWA post-ban lower with all internal parts installed matched up to a Colt A2 upper with the following parts installed rear sight, forward assist and dust cover, charging handle and delta ring also included.
I had the part refinished by a gentleman down in Arkansas, so all match.
Lower is marked:
CAL 5.56 MM
The colt upper is marked: C MB by the rear sight.
I had intended to make a post ban M4 out of the two parts. But decided to buy a Remington 7400 instead. I have a picture if interested that I can email to anyone. I am asking $280.00 shipped to your FFL dealer. I will do a face-to-face sale in NC.
