Spikes new modo "Not what we used to be"
by Michael -
Purchased a zombie spikes lower and this upper separately from PA back in 2015 and the fit was extremely tight. I still have that rifle and it feels like it's one piece, rock solid.
<br>I had a 2nd Zombie lower so I ordered the spikes BCG, upper, & buffer tube to replace cheaper parts. Bottom line - I'm not happy at all. As others have noted there is an abnormal amount of play. I installed an accuwedge in mine and that wasn't even enough to remove the play. That's how bad it is. An Anderson upper and lower fit together better than this crap. If it weren't already put together and loc-tited-up, I'd ship it back. Now, not worth my time.
<br>This is no reflection on PA. PA shipping and service is great. Been a long time customer and will continue to use them.
Impressed, no complaints

Purchased one at a great discount. Also purchased a Spike's lower at my local gunshop. I enjoy this upper quite a bit and I really have no complaints at all.
<br>The play in spike's upper/lower combos is extremely minimal. Definitley not enough to cause any concern. Any body complaining about play at this price point must be quite a snob. Any upper/ lower combo is going to have some play. And there is plenty of ways to fix that if you are really that concerned.
<br>The finish is great, I've treated my AR like it is a tool (1,000+ rounds), not a trophy and the finish on this upper has remained high quality.
<br>With that said, if you're trying to build a pristine multi-thousand dollar rifle, then shame on you for cutting corners and then complaining about it.
Shame on spikes
I was very disappointed. I figured that Spike's uppers would be just as good as there lowers. I was wrong sloppy fit .last 2 uppers I will ever buy from Spike's....

I purchased this Spike's upper to use on my Spike's lower. Has alot of play. The inside is not finished very poor finish on the outside. Tried installing 3 different barrels and all had play and had a loose fit. For the money I payed I hoped for a better product from spikes. Very disappointed. May not be safe to use as barrel fitment is very loose. On a brighter note primary arms delivery was fast.
Poor quality, how did this pass QC?!
Bought this upper for a recent build because my lower is a spikes crusader and I love their lowers so I figured there uppers must be just as good... I was mistaken. Got this thing and inspected it and found a few disappointing issues. There was a little chunk taken out of the threads where the barrel nut screws on, but it was shallow enough where it doesnt mess with the barrel nut. On both sides just under the rail there are long deep scratches going from the front to the back of the receiver and the inside looks almost like there’s no anodizing at all. Not to mention the bottom of the receiver looks like the anodizing is about to pee off? Definitely not impressed at all. Will be sticking to bcm uppers in the future
Spikes upper poor fit
by Will S -
Lousy fit to lower. Probably out of spec. Gap so large between upper & lower, you could see through it. Disappointed.
Best price I've found anywhere. Fast shipping.
Great fit with Lower
by ReelConquest -
Just as I had expected from Spikes, excellent quality, looks to be 100 percent. Fit perfect with my Spikes Lower, nice and tight and the finish match was right on. I was a bit surprised that it came in rather cheap back like used for other parts but just figured the upper would come in a box like my lower, I could be wrong but I think all their parts will be in these white bags now. Shipping and service was top notch as always.

Great match to my Spikes Spartan lower!! Fast ordering process and delivery!
Very poor quality. Shame on Spike's for selling this.
Waited for a while for these to come back in stock so I could finally finish my all Spike's build. I was super excited to get this in but that turned to shock when I unboxed it. I could not believe the poor quality of this upper when it arrived. The finish was awful and not even close to the Spike's lower I had for it. The machining lines were off and looked like it should have been a blem for half the price I gave for it. Spike's has always been a great company for me but after this I may look at other companies that are just as good (maybe even better now) for less money. After paying big $$ for their NiB BCG that was staked very poorly and this upper I'm starting to wonder what's happening with their company.
I have three lowers and four uppers (not including this one) all from different manufacturers. This upper is the loosest fit of all of the uppers I have. The finish is fine but the fit is marginally acceptable at best.
This upper receiver is very well made. My one and only issue is the finish. It scuffs up easily and just doesn't look as sleek as I would have expected. It almost has a dusty black appearance rather then straight black as I expected. I actually considered sending it back because I have a Black rain ordinance upper with a very nice finish that does not scuff and just looks sharp. In the end I kept the spikes tactical and got over the issue with the finish. Overall I would recommend.
Fit perfect on my Spike's Tactical Spider lower Receiver. Have had no issues yet with it and everything fit nicely. As always it's nice doing business with PA and it's lovely to be in Houston to pick up at the store and save on shipping. I'd recommend this upper for anyone who just wants a good solid standard upper for a good price.
awesome spikes upper!!!!!
This upper came fast & is marked by a good forging company. Black as it gets not a flaw in finish. Fit is great!!!! 110% HAPPY with this upper!!!! SPIKES TACTICAL & PRIMARY ARMS ARE BOTH GREAT!!!!!!!
I bought this upper to mate with my Spikes lower (spider) as both are Spider and the fit is Sloppy as in a lot of play.. if I mate the upper with my S&W M&P 15 Sport lower the fit is tight if I mate the lower with my S&W upper the fit is tight but together it's bad Sloppy and this was my first Spikes purchase and my last.
I have purchased this item for my latest build and found out the receiver hole was undersized and didn't allow the AA piston op rod to slide through. I had to use a manual press to ream out the hole to .195" to allow the rod slide smoothly. This reason why this item received 4 stars instead of 5.
very good for $
by Robert Stevens
Fit & Finish is always really good.
looks and feels great, have not installed as I need other compotes still. no flaws!
Very nice upper
Very nice 100% in spec upper that I use for every upper I build my self. I'll always gravitate to this upper for the quality and price. Buy with confidence.
