Price point compared and quality great
I just purchased a FN M-16 retro military rifle and comparing the two uppers, the Aero is much lighter and looks almost the same. I would highly recommend Areo as an excellent choice for this style.

Really nice barrel
When I opened the package, I put my borescope into the barrel. I was pleasantly surprised to see really smooth, shinny rifling - - and a gas port completely in a groove. The hole was not centered in the groove, but it did not cut into the land. I wish more manufacturers knew how to make such pretty rifling. The bore did not appear to be chrome plated - - better for accuracy but worse for wear and corrosion resistance.

Aero Precision AR-15 upper
First thanks to Brownells, fast shipping, packaged with care. Other than that Aero Precision products are top notch, especially when on sale.
