like the title says.
This is a new 20" upper. Ive personally have never mounted it and i dont think the previous owner did either. firing pin is spotless.
comes complete. with halfmoon BCG. bcg has some streaks that seems like it has been racked a few times, so it may have been mounted.
I am not 100% sure if it is a prepan upper. The box says R6551 DC as the model and .223 as the caliber.
The barrel says C MP 5.56 NATO 1/7
No bayo lug. The link I have provided has pictures of the markings on the different areas of the upper
here is a link to my Google picture album of this upper
