Great

by

I've used this upper for about five years now. The only problem I ever had was a Tula round glued to the chamber after excessive rapid fire along with my buddies MP15, and mine cleared much faster. I rarely clean this upper and shoot a lot of 22lr through it, great upper with quality comments.

very pleased

Very fast shipping. PrimaryArms never fails! This upper is worth every penny and of course the quality of spikes speaks for itself!

Made for hard chargers.

First of all I have to say that Primary Arms is a top notch outfit. Super fast delivery and easy to use website. This Spikes tactical M4 upper is worth every penny. It comes with a M-16 bolt carrier group and the entire upper meets high standards in testing. Some don't realize it but the M-16 bcg has more metal in the back end than the AR BCG giving it more heft. The upper fit tight with my Spikes punisher lower and looks sharp. The BCG is made to tight specs and this required a break-in period as most tight spec BCG's do. A good cleaning followed by some oil and a good cycling of the charging handle and rounds down range had it running like a sewing machine. Very pleased with this product and Primary Arms packaging and service.

Very pleased with purchase

I added this complete upper to lower build using a Spikes forged lower. This upper mated perfectly to my lower build - tight with only the smallest hint of wiggle. Fit and finish are superb... Barrel made by FN... Premium Spikes BCG and bolt... What's not to like?Highly recommended if you're looking for a quality M4-style upper at an attractive price.

Awesome!

by

Put on my M&P 15, and it works flawlessly!

Love it.

First AR I've built and Spikes hasn't let me down. Would look nicer if it had a smaller hand guard on it, but, that was easily remedied.

Spikes upper

I have made smaller purchases with Primary Arms before so my expectations were naturally high. Those expectations were exceeded by the upper receiver arriving ahead of schedule. Better than expected is becoming increasingly expected!

Excellent

by

This has got to be one of the best deals on the internet or anywhere else for this upper. I can't find it better priced, it may be out there but I've ot found it. Also, Primary Arms has one of the best customer service orientations I've run into. They say they answer questions 24/7 - I sent a question at 3:30 AM on a Sunday morning and I had an answer in 15 minutes - not one of those "we received your question and will get back you" responses you normally get. They shipped early on the first week day after my order and it was here in just a couple of days. Everything I ordered was there, in brand new boxes, and the order had been checked by at least 2 people before it went out. I'll buy here again, and have it as one of the few web sites that I've bookmarked on my computer. John

Spikes complete upper

I'm very happy with this upper. It showed up three days after I placed the order. This weekend i'm going to take it out range. It fits my m&p 15 lower perfectly. Feels solid and looks nice.

A+ upper and service

by

I put this upper on my spikes punisher edition lower. Excellent quality and smooth operation. Have put 120 rounds through it with no FTF or FTE. Definitely exceeded my expectations. And primary arms was lightning fast on shipping, ordered on a Thursday morning and received on Saturday. Will be getting some primary arms optics soon to go on it.

Great deal,Nice upper !!!

by

I decided I needed a couple of uppers for my builds.I saw slickguns had a coupon for 15% off spike's.I knew and have ordered from Primary before,good deal then as well.I ordered it on Friday.I received it on Saturday.Came by rocket ship apparently!!!Very nice upper,all spike's and no blemishes that I could find.So guess what ,I just ordered another one before sale ends.I really don't need it,but I feel I cant afford not to order 1 more lol.Thanks Primary and happy MO day everyone !!!!

Spikes carbine upper

by

Wanted to do a simple build, so I went with the spikes carbine upper. I have a complete spikes carbine and it's good kit, so I decided to go carbine rather than middy(I have a bcm middy) for weight purposes, quick shipping and good comms by PA, was able to finish my final build, paired it with an h2 buffer and I'm good to go, took it to the range, zeroed it. Put a 100 rounds through it and it's gtg. Got this during the salute to Texas sale so I got 200 rounds of xm193 to boot. Everybody wins...

I needed this upper to complete a spikes lower receiver I had built. Primary Arms was the only place that had any Spikes uppers in stock period..... The price was great and I received it very quickly and in fine order. I will be buying from you guys in the future, definitely!! Thanks allot , you made my gun exactly what I wanted.

Spikes Complete Upper Order

by

Primary Arms has earned my future business. They had the Spikes upper I ordered in stock as stated and at a good price. They shipped it out super fast. Product came in just a couple days and just as described.

Great Products - Great Prices - Fast Shipping -

by

2 orders in a row, 1st order was a spikes upper, in my hands 2 days later, 2nd order was a Primary Arms 4-16x44 scope, in my hands 2 days later, mounted it and zeroed yesterday, good glass, holds zero after 200 rounds of 308 handloads. Very happy with products, prices, and shipping. My order from another vendor is still pending shipping after 2 weeks.

Very High Quality

by

Thanks again for such a great price and fast shipping! This upper is second to none, the fit and finish are great, and in side by side comparisons with other uppers in this price range, the spikes wins every time!

Spikes tactical 16" st-15 m4 le upper receiver

by

Excellent customer service and delivery. Looking forward to ording more items soon.

Great product, great shipping

by

Ordered a Spikes LE upper and received it 3 days later. PA was the only place I could find this upper in stock. Great job keeping stock in these difficult times.

Super deal

by

I never submit reviews unless I am totally impressed by a product. Well, I am totally impressed! I put this upper on my S&W MP 15 and it fits nice and tight without any play to the lower reciever. The bolt is very rugged, and the double shield handguards are a nice bonus. The keyhole forging mark is present on the upper, and it has the proper 'F' marked mil spec sight. Its an awesome deal. Hope this helps.

Prefect fit and finish with my DPMS lower Thanks Primary Arms

Can't go wrong with Spike's

by

Great upper. Takes everything you feed it, including low powered steel cased ammo. Cycled without a hiccup. Accurate barrel. Quite pleased with this purchase.

Spikes M4 upper - great

by

Mated w/ a Spikes lower...they fit tight ...as they should...also replaced the M4 handguard w/ a quad rail and added Magpul rear sight...Very happy...Also, Primary's was tip-top!!

Spikes quality disappointment

by

Shipping was fast. The Spikes upper did have large scratches in the finish when I removed it from the sealed plastic bag. I don't think Primary arms knowingly sent me a "Blem". More likely Spikes sent it out the door 'as is'. I will just live with the scratches and shoot it. Heard lots of great things about Spikes, but I won't buy their brand again. Primary Arms will get my business- they have good service!
