Outstanding these bolt gas rings from *BCM hold the gas very pleased with them. It is like a new carbine now. Thank you *BMC
Mix up on first delivery attempt, most likely USPS fault, but after contacting bravo about it had a new order delivered in 3 days no extra change. 4 stars simply because there's always room to improve.
It's always best to have extra. This was the best place I found for the its price compared to other sites.
I have found the BCM rings to be the best on the market and the only rings I trust.
Great to keep in the spare parts bin
Great way to get a bunch of spares!
Purchased these for spares, excellent price and fast shipping
Bought as back ups.. cant have brought backups
It was a quick delivery & a great quality product! They made a noticeable difference on my rifle!
