best company ever...


I purchase most of my parts for my gun from Primary Arms and every order was awesome. Fast shipping and customer service is great. By far my favorite place to get parts for my gun. Keep up the good work.

Good Upper


I purchased 2 Andersen Stripped Uppers and I am impressed with the quality. I haven't built them up yet but they appear to be just as well made as a couple of Aero Precisions I have in the safe.

Anderson AR upper


I purchased 3 Anderson MFG uppers for an AR build. They were very good quality and were shipped the same day I ordered.I would recommend Primary Arms to anyone.

Anderson Uppers


I purchased 3 upper and place them on my Anderson lowers purchased somewhere else made to fit and would buy again if on sale. No problems fitting Barrel, barrel nut and hand guards. No slop nice fit...

Anderson Makes Some Quality Parts!


I purchased several of these and have to admit that Anderson puts together some quality parts. Do not be deceived by the price, as their parts rank right up there with the best forged parts on the market. I would definitely buy again.

Great quality at a great price.


I purchased this for a lot less than I've paid for other uppers, and to tell the truth, it's hard to tell them apart. I haven't had the time to really field test it, but everything fits like it should and it looks like an inspected and finished product. No nicks, burrs, or blemishes at all.Also, PA has had some of the best customer support and fastest shipping of anywhere I've shopped online.

Anderson uppers


I think these are a great investment

Anderson Manufacturing Stripped A3 Upper Receiver


I usually purchased my uppers elsewhere, but since I've purchased four stripped AR15 Anderson lowers with good results, decided to give Primary Arms the nod with an Anderson stripped upper.Good service.Good product.Good price.Shipping was awesome!

Upper reciever review


I was a little timid to try it at first based on the price but figured for the money I would give it a shot. Very good quality for the money all parts fit properly and operate smoothly no complaints. For the money you can't go wrong.

Great product at an awesome price.


I was kinda hesitant to purchase these items not really knowing much about the manufacturer but I gotta say I was very pleased with the price and the fit and finish of this item. Deep color and it looks as though you'd pay twice what was paid for it. In short good quality great price. Will be ordering several more after I order my M5 upper and lower set.***** *****For the record the transaction with Primary Arms was one of the best I've ever had. Thank you for you speed and professionalism gentlemen.
