Does what it should


Not much to talk about works like it should. Easy to install functions well. PA has the best price

All works no looks


Functions as it should but boy is it ugly. I bought this to match my Areo Upper but it didn't match at all. If you don't mind things like this don't worry.

Everything fits and functions as it should. The oil or grease that is on it to protect it was kind of a pain to get off in the crevices on the ejection port cover. Matched my Anderson MFG. upper. Great quality for the price point I think.

Upper parts kit.

Shipping was fast, everything was as it should of been. Parts work perfectly for my build.

E Clip preinstalled

by -

I enjoyed having the e clip pre installed on the ejection cover hinge rod. I have lost one previously while installing. It was there one minute and the next it sprang off never to be seen again. Roll pin fit nice and tight in my aero upper.

It is what it is

No frills standard upper parts kit. Everything fit as it was designed to. This went into a stripped Anderson upper.

Quality, affordability.

by -

Fit and finish are exemplary for the price you pay. I paired this with a WMD Guns AR upper receiver with no installation issues.

Great product

by -

This kit is good. Was super easy to install and looks great. Also primary arms ships things so much faster then anywhere else. I bought this for something I ordered like a week earlier from a different web site and this stuff showed up first

Good upper parts for a decent price.

Great stuff from Aero, even a better deal when on sale. Can't beat the price or quality.

no complaints , its upper parts

no complaints

Incomplete parts kit.

by -

Kit was missing Forward assist roll pin. The plastic baggie had a hole in it, so it probably fell out. The remainder of the parts were accounted for, and appeared to be good quality. This seems like an anomaly as my other purchases here have been great. I'll email customer support and hopefully they can make this right.

Great kit

Great kit for a stripped upper. All parts were present. All parts installed just fine and function just fine. No complaints.

Exactly what you'd expect

It's an upper parts kit, there's not much to it. I did appreciate the black spring for the dust cover which looks a lot better than a silver one in my opinion.
