I got the upper as a gift
I got the upper as a gift for my birthday and was super excited to put it to use, opened it up and it was a used upper. You could see where it had a dust cover installed and it looked like it had been used for a year. the inside was all wore where the bolt carrier cycled and my barrel wont fit in it without putting all my weight on it. they claim it is hard coat anodize (it isn't)the black scratches easy. very disappointed in this product, save some money and get a different one.

The finish is great. Howe
The finish is great. However, the take town pins have alignment issues on a Spikes Tac lower, a little better on a Rock River lower.
