Favorite upper04/22/2017 ByJD I have been through a number of builds & I am most happy with this perfected upper. Some may not believe there is much of a difference, but I can tell you when i built one with an Anderson upper I new right away my Aero's were several notches ahead. Just the finish alone on Aero is smoother & the fitment feels more precise. Barrel nut threads on the Aero are ifhigher quality, no grit. One of the biggest things I have noticed is how after I build an Anderson the finish wears very quickly off the charging handle without shooting the first round through it. YES I lubricated during assembly & the Aero's can go on to shoot a good 100 rounds without noticing any wear on the same brand charging handle. Just the little things sometimes that are nice. Waste no time & buy your Aero upper from the Armory today. Very pleased with the service of the Armory folks!
