First off... Thank you Aero_ Precision for the 10% military discount.
The upper is great, it fits great on my build lower receiver. Great shooting and accuracy. I highly recommend this upper for anyone building a short-length AR-15. (Posted on 2/23/2016)

I got my upper when it went on sale. What a great deal and the quality is top notch. Can't wait for my lower to get here in a few days. I will be getting another in 300 black out as soon as this build is complete. A++ (Posted on 11/13/2015)
