Milspec Carpenter No. 158® Steel
Needed this for a build. Worked perfectly. Like doing business with the folks form Bravo
Spend the extra few dollars and buy the BEST quality parts. I just purchased 2 extra bolts for my BCM builds. I always tell people, you can find fancier gear, but nothing is as good as BCM! Highly recommended.
This bolt is excellent. I appreciate the prompt email follow up to my questions so I would purchase the right product.
Nicely machined bolt. Comes with an O ring. The extractor spring is stiffer than the mil spec according to BCM. So you may not need the O ring.
I've built a few ARs from readily available parts and kits. But since then, I've become much more educated about the junk most of these kits include. I wanted to increase the quality and reliability of my guns so I purchased a complete BCM upper for 1 rifle and I've been changing out critical componets on my other guns. Barrel, bolt, trigger, etc. BCM quality can't be beat. A bit expensive, but so worth it.
Well made product and will keep buying from this company.
It's a great AR-15 bolt Works great in my rifle it's a very good price for such a high-quality bolt
BCM's quality on their bolts and BCG's is the best value for the money in the industry. This is always my go to bolt.
BCM has an excellent reputation, so when I wanted to purchase some extra bolt assemblies, I chose them.
