Colt 9mm upper
The upper I received looked a little beat up, I didn't see the normal "police trade in" in the advertisement so I assumed it was new.

Fantastic price on great upper
This is the real-deal, folks, great for your retro build. The package also included the appropriately weighted buffer and spring, which are a great value themselves.

Inaccurate description....great 9MM SMG Upper!
I was expecting a used R0991 Colt 9mm SMG upper receiver assembly but actually received a rare Colt R0635 assembly manufactured in the 1990's. The unit was in excellent condition and I couldn't be happier. Whatever PD had this SMG was very gentle with it. Thanks AU!!
