Good upper great price
I received this upper today. I intend to paint the rail to match the FDE scheme on my rifle.

The only small complaint is that the top of the rail is a bit lower than the top of the upper receiver. It's not significant and honestly it won't impede what I intend to do with this setup. If I had to guess i'd say it's a few hundredths off. If I had to bridge it I may be worried. But even with a front and rear iron sight it's such a small difference that a couple turns of the front post will correct for it.

I really like the look of the 12" rail on the 10.5" barrel with the flash can. I was worried that it may not look like the photo but it does. This seems to be relatively well made and I'll be sure to submit an edit to my review if anything odd happens during live fire tests. I paired it with an Anderson Lower and it matches nicely in finish and fit.
