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.

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.
