Your bolt carrier group is one of the most critical parts of your build. Don't buy an imitation. Spike's Tactical AR-15/M16 Nickel Boron Bolt Carrier Group.

The gas key is properly staked, the extractor spring has been upgraded with an O-ring for increased tension, and all surfaces are coated with nickel boron. Nickel boron is much easier to clean and can help your firearm run more reliably when heavily fouled or with little lubrication. The Spike’s Tactical Spider Logo is engraved on the right side of the carrier to show through the ejection port. Assembled BCG weighs 11.6 oz.

BCG Just what I needed

by

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.

Blemished Finish

by

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.

Runs great, cleans easy. Primary Arms has the fastest shipping known to mankind, but they don't include any free swag(tshirts, stickers, patches) if I ordered my Geissle trigger from the manufacturer is get a whole swag bag. I put in a 700 dollar order, I thought I would get a sticker atleast.

great product

Spikes quality is amazing. Primary arms has great service and fast shipping

Spikes Tactical always delivers with quality.

Spikes Tactical makes some of the best rifle parts on the market. I bought this for my Spikes Tactical build I'm doing now. Usually I would not go to the nickel boron, but this is the rifle that I am going to constantly carry, train with, teach with, and be my everyday rifle. Having shot with nickel boron parts before, rifle cleaning is so much easier.
