“Been using these for years, never had any problems, fit and finish are always immaculate, when paired with a Aero Precision lower they fit perfectly together and with the adjustment screw in the lower you can take out any play or wobble on finished assembly. In my opinion You can pay more for a upper/lower but you won’t find a better one than Aero Precision.”
“Simple standard upper receiver, machined nicely with all tolerances set to fit my lower and no issues running it. Aero makes good stuff for good prices.”
“It’s a quality piece at a reasonable price. Barrel fit was pretty good; it could’ve been a little tighter but that’s how tolerances goes from piece to piece. This is my overall go-to receiver nowadays when I can find them at a good price. You can’t go wrong with Aero Precision.”
