Spike's Upper is Top Shelf!
by Ken6PPC
I have built other uppers, but Spike's quality is among the best. It shows up in the finished upper, so I think it is worth the extra cost. And, of course, PA is the BEST place to buy....
A great upper
by Selby Philipose
I love the quality and value that the Spikes upper offers. Add to that the great customer service offered by Primary Arms, makes this a great upper for anyone building an AR15.
Best Service
by Horace Temple
I must say this has been the best service I have received from an on line company. My upper was in the mail with a tracking number just a few hours after I place the order. Thanks

I purchased this upper for my custom ar15 build and it mated perfectly to my bushmaster xm15 Lower receiver. Shipping was fast. I will definitely be ordering from primary arms again.
Bang for your buck!
by Eddi Medero
I was looking at other uppers and I came across this one. I was a bit skeptical at first but when I received the product, I was blown away how sturdy it felt. 8 took it out to the range and shot a few rounds using a Melonite bolt. The action on this is extremely smooth compare to other uppers. I am completely satisfied!
Speedy delivery and Great customer service
by Sean Cooper
I was very impressed at how fast the package arrived. I had made some mistakes in the delivery instructions for a stripped lower and PA took care of it, and sent the package to the FFL. The only downside is that, unlike other websites, it didn't come up with a list of FFLs near me when I went to check out. That would have eliminated any confusion. I've ordered several things from PA and I will order more in the future due to the ease, very fast delivery, and best prices I've found for my parts. Would definitely recommend.
Upper receiver
by DAVID LUNA
I was very impressed with all facets of my dealings with Primary Arms. This Spikes receiver fit and looks perfectly mated with my Rock River lower. The shipping was very fast and the item was well packed and unblemished in any way. The price was right on and the customer service was superb...I will deal with again no problem and I recommend them totally and with no reservations!Thank you for a great experience A+++
