Your bolt carrier group is one of the most critical parts of your build. Don't buy an imitation. This is the same BCG Spike’s uses on their builds. These complete bolt carrier groups come magnetic particle inspected and high pressure tested. The carrier is made from 8620 steel and the bolt from no. 158 carpenter steel or 9310 depending on supply. The gas key is properly staked, the extractor spring has been upgraded with an O-ring for increased tension, and all surfaces are MIL-SPEC heavy phosphate coated or internally chrome lined. 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.

Good Stuff!

Works as expected and if it didn't, Spikes would make it right. I prefer Spikes Tactical due to their quality but their customer service is outstanding as well.

Gas key not staked

by -

I’ve never used any spikes products, but have always heard and read good things about their products. Staking the gas key is being done by even the cheapest manufacturers now, and isn’t something that I would expect spikes to overlook. It makes me question the overall quality of the bcg. Spend the extra money and get a BCM.

From PA: That is not normal. Please get in touch with us so we can get you swapped out with a properly staked BCG.

The best

by

In the past, I have always used the BCM Gunfighter BCGs. I decided to try the Spikes Tactical after reading some very good review and I was not disappointed. Everything is as it should be. Very nice fit and finish.
Great product, fast shipping and great price.
Primary Arms and Spikes Tactical are the best.

Quality and Performance

by -

What can I say. It is Spike's and it simply works. No head space issues, no staking issues. It has cycled every round I've thrown at it without fail.

Best Dollar for Dollar

by -

I've purchased two of these as of today August 28th 2018. I got the second one because the first one has worked flawlessly. I put it in a Spike's Tactical custom build for my wife in 300 AAC Blackout. We've put a couple hundred rounds trough it. No FTE, FTF, or malfunctions whatsoever. High quality, good price, made in USA.
