Spikes Tactical BCG W/ Nickel Boron Coating
by Dan C. Watkins
After years in the US Army (now retired) and having had BCG's in M16 that always seemed to get so horrible dirty after shooting on ranges. I wanted to make life easier for me with my Ar15 at home. The BCG coated with Nickel Boron is like nothing I've ever dealt with before. It is truely awesome and can be cleaned almost just by wipeing with a clean rag. A must have for anyone who's concerned with making easy in the cleanup after firing!

Always a pleasure going to primary arms.nice quality bolt carrier group for your money.
BCG looks good, slightly different than the last Spikes NibX I got, different machining/look... But still a quality piece. The first I got was missing a gas ring and the remaining rings were damaged, but PA took care of me... This BCG came complete, but has more of a rough overall appearance. Happy with it though.

Spikes Tactical Bolt Carrier w Nickel Boron
Excellent service as usual, fast delivery!
by Nicholas Case
Finished my build and put it in and it was great, until I function checked. When I let the hammer fall it jammed, would not extract and the bolt would not rotate even with heavy lube. Took disasembly and force, tried it in factory Colt, DD, and Stag. Same prob. My BCM bcg works fine in my build, but wanted NiB. The part I got seemed to be machined to the wrong specs (I know that FailZero coats some of these products, and I read a post by their head gunsmith that stated that if the bcg does not fit you need to have your headspace checked that it is not match grade and is instead mil spec as these bcg's are patterned after Colt style rifles... But it would not work in my colt?). Returned to PA for refund. They are out of stock. How does that even leave Spikes Tactical not functioning? I have to add that PA is still the great. They handled it well, gave me return shipping labels and a full refund. I will try another when in stock.
spikes tactical nib bcg
by Andy Davis
Great addition to my Spikes AR.......probably wouldnt have got this but saw it on sale and was still below 200 bucks after shipping. I know Spikes makes quality products and PA has great prices and fast shipping, what else could you ask for. Thanks for the free hat too.
Great bcg came faster than I expected.

Spike BCG Nickel Boron
Great service. I sent in a E-mail to see if this part was in stock and the next day they sent me a E-mail saying that they did have them in. I placed my order and waited and next thing you know after a bit of time it was in my hand! I wish Google would had come up with this site. I don't know why it did not but after looking around all over the net using all sorts of keywords I found this company and it had my part that I was looking for! This place is Real and you will get your stuff!
Spikes nickle boron bolt 556
by Garrett Comer
Had been trying to find this bolt for a week. EVERYBODY was out of stock, even called spikes directly w no luck. I found Primary Arms online, and guess what, they had it! I ordered it for a great price, and got it in a few days. Very happy! Great prices, fast shipping!
by Jeremy Watson
Havent installed it yet, but BCG looks great, great machine work
by Robert Aguilar
Haven't used this thing yet but heard nothing but good things about it. So far, all is as expected. Finish was not as aesthetically clean as expected but not too big of a deal.

I am currently building an AR pistol and these guys have the fastest shipping anywhere. I've placed many different orders with them and very one of them has shipped same day and arrived max three days later. As for the product, its spikes so you know its quality and its exactly what I ordered and what got me to the site was some of the best prices on the web! Thanks Primary Arms!
Been waiting for the price drop
I like Spike's BCG's they are well made. While I wouldn't pay $209 for one, I will spend $169. I have been waiting for these to go on sale for an all Spikes build I was working on. I still replace the extractor spring with the BCM spring, now its perfect!
by Frank Gaddini
I ordered this Spikes bolt assembly and it was in my AR three days later. The service was fast, I mean really fast; and the product was awesome.

I was amazed to find the item I was looking for in stock, for a great price, and was shipped fast. I wish more companies would utilize USPS Priority.

BCG Just what I needed
by Michael VanderMey
Ordered a Spikes NIB BCG to replace a problem DPMS BCG. Great price! In stock! Fast shipping!You guys seem to have more inventory at good prices then everyone else. I really needed this part because to have a personal defense weapon that is not dependable can get you killed! Now it cycles like a champ. Thank you so much.
Happy happy happy

Ordered late evening on Friday november 28 and received it on Monday december 1. Customer for life now! Thanks primary arms! Building a nice lower for myself using spikes products!

Purchased one of these brand new and when it arrived I was surprised to find what looks liked small, but obvious rust spots showing through the carrier's finish. I could feel these spots with my fingernail, but couldn't clean off with any kind of solvent. Something must of happened during the NiB process to cause this because this finish is supposed to be very corrosive resistant.Primary Arms worked fast to put me in contact with Spike's who quickly handled the situation well and had me send in the BCG for a new one. However this took an additional 2 weeks time to complete. The replacement bcg I received has a better looking, flawless finish and seems to work great.
