Ratings & Reviews
I'm glad I bought this
I have had this upper since June 2018, it has not failed once. This upper sits on an Aero lower with magpul furniture with a Strike Industries 17-7 flatware spring and an Expo H3 buffer. Being skeptical, I started with a Simmons 3-9x50 optic, then a Nikon 3-9x40 Prostaff and now an ATN 4K Pro 5-20. I am pleased to say the this rifle is a tac driver whether its Winchesters Hog round, Hornady SSTs or even Tulammo. Hey PA, if I could upload photos?????
Very happy customer!!!
Just finished putting it together with my stripped lower. Every went together perfect. All of the parts looks nice and packaged good. I received it very quickly. I will definitely by from them again.

Upon opening the quality is just amazing for what I spent. No rattles or clanks from the upper. After assembling there are no noises or freeplay from the lower and upper. Really solid.
<br>Firing the weapon is AWESOME. I did switch the Muzzle Brake tho to a JP Enterprise Large Brake for .308s. ( no muzzle rise or sway ) I would love to post pics on here but I cant. So I left it to Twitter @random6uy.
<br>Primaryarms.com has OUTSTANDING service. They have my business.
Not worth the aggravation

Very disappointed in this purchase (my first from Primary Arms, perhaps my last). The upper arrived looking like it was assembled by a group of blind chimpanzees (scratched, loose handguard, and poorly installed gas block). The LPK was total crap as well, utterly useless -- doubt it is actually milspec -- and missing parts (two detents, disconnector spring, and takedown spring). Minimalist stock so badly misshaped that would not fit on buffer tube.
<br>On the positive side, after reassembling, replacing bad/missing parts, polishing feed ramps, changing out BCG, etc., it performs adequately. It just cost more (both in $$ and time) then it was worth.
<br>From PA: We're sorry that you had this issue, but glad to see that you're up and running. Please let us know if you ever have an issue with a product you purchase from us. We'll be happy to take care of it for you.
Best AR 7.62x39 build kit. Radical Firearms is AMAZING!
by Kyle -
This is the best pre built AR 7.62x39 conversion rifle you can buy for less than $500. It has NO light primer strikes and feeds perfectly with any mags (I'm using ASC and D&H Tactical mags) if your mag doesn't feed smoothly, put some clp on the follower and spring. Be AMAZED as it eats steel cased (Tulammo, Red Army Standard) all day long. Only time it wouldnt fire was when I came across a dud. (I re-fired it 3 times and nothing, so it was a dud) I am in love with this rifle. I wanted a MK-47 but they're to expensive. This is (w/o being able to use AK mags) like a Windham Weaponry in the AR firing 7.62x39 talent show!
It's running fine!
by James not Johnson
This kit is a great value with the upgraded stock, slim mlok rail, and brake. It's been running good so far no issues ~300+rds. I did add a heavy hammer spring (from brownells) and use RZE multi mags.
