Anderson Manufacturing Upper
by Jimmy Callins
Good as any. Nothing special. Arrived on time in good condition and fits my lower. Haven't completed the upper build yet.

A good quality basic upper at a great price
by Michael Diaz
After shopping around for an upper receiver I decided to go with this Anderson because of the lower. The fit and finish was perfect and so was the color match too.
by Fred Scofield
All part ordered were for my first AR. Since AR10T's were ridiculously priced I decided to make myself a 300 blackout. PA was the only company that had a complete upper in stock.Thanks to them I was able to complete my build in about 10 days. Totally satisfied.

As good as any other top tier upper on the market. Fit and finish our excellent. Honestly, I was skeptical at first, but I am a believer now! Buy it, you won't be disappointed.

Quality uppper at a good price
by David Yearick
Bought a few, went together with spikes and anderson lowers perfectly. No visible nor functional flaws.
Bought this for a friends build, after using a few for my personal builds. I have used dpms, rock river, bravo company, and many others and they all have been equal iin quality, and function. Tight fit to the am15 anderson lowers, m4 feed ramps are correct, functions as it should. Would recommend, and I will probably use them again.

Anderson Manufacturing A3 AR-15 Flat Top Upper Rec
by Roberto Roxas
Fast Delivery and saved me time and money from assembling wished PA would do another sale soon, I need two more!
by Ian Delfine
Fast shipping, great service, great price, product is beyond words. Will ALWAYS look at Primary Arms first for all my needs.
mounted nice to Spike Lower
Finish is good, no markings on picanney rail. But was impressed with how little slop there was when mounted to Spike lower. My spike upper has way more slop. Plus on sale. Haven't assembled it yet but so far would buy another.
Anderson A3 AR15 Receiver
by Brian Dunn
Fit and finish are excellent. A little upper/lower rattle which is to be expected because it must fit every lower out there. Rattle is eliminated when an accu-wedge is used. Delivery a little slow but this falls on USPS not PA. All things considered - a lot of quality for very little money.
great price for an upper reciever
by Samuel Smith
fit and finish look just like any other upper, but for less $$$. Great deal. It is a little extra black in color, but most my anodized toys have seen sunlight, use, and cleaning.
kinda loose fitting
by william thompson
fit and finish was not that great but is tolerable. you get what you pay for i guess. all other products from this company have been great will still use for parts
