I have to say, the finish is great. The Build is what you would expect Aero. I would am pleased overall. I really can't really complain. Great product overall. The muzzle break is really nothing special, but it will work.

This week I built my first AR. I decided to use all Aero components, and I was not disappointed, Works like a charm. There’s a lot to be said to use the same manufacture . For the money you can’t beat it. I would buy this again. The hand guard is awsome it’s light weight and plenty to work with when adding ginger bread.

Very high quality, and really good for the price point. It’s caused me no problems so far, even though I’m only a couple hundred rounds in. Pin point accurate at 50 yards.
