Fast shipping/great product
by Kenneth Bankston
Great upper to go with my Spikes lower, super fast shipping. After processing it took a day to get to me with normal shipping. Will do business again.

Upper is top notch
by NICHOLAS SELLS
I bought a spikes lower from a local gun shop and decided to order the upper due to better pricing. The fit to the lower is outstanding with barely any play whatsoever. Primary arms speed has got to be the best out there, I placed my order at night and I think it was a weekend also, and received a shipping notification what had to of been a few minuts later.
Had an issue
by Brian
I bought two, one was out of spec. Spikes is swapping it out for me. 4 stars just bc of issue with manufacturer defect.This was my first purchase from Primary Arms. Excellent shipping, good communication. Very pleased and will buy from again.
Great quality
by Christopher Hutchison
I got this during the Black Friday sale and I'm glad I did! I built a 300 blackout and used a generic blem upper. Does it work? Yes. Is it a nice looking upper? No. There really is no comparing the two. The Spike's just screams quality and is completely flawless. Definitely get it if you're on the fence. You won't regret it.
Spike Upper
by Martin Froymovich
I have a factory complete Spikes upper on a factory complete Spikes lower. The fit is the sloppiest out of any of my AR's. I tried the lower with some of my other uppers and they all mated up very well so I figured I would put a new upper on my rifle to remedy the poor fit. I ordered this upper and it won't mount to the lower. I tried it on 14 other lowers I have, with no luck. The front pin hole is out of spec. This upper does not have any markings so I don't know what company it was casted by. I have never seen an upper without markings until now so it makes me wonder where Spikes is getting these garbage uppers from. I think I'm done with Spikes Tactical. There are to many other AR parts manufacturers out there that I've had much better luck with.
NICE!

I have been waiting a long time for this item to come back into stock...and was not disappointed. This is going on a 5.56 20" Very nice and clean. Fits perfectly with my Spike's lower. Great product and Awesome service from Primary Arms. I am looking to use same upper for 300 blkout soon.
