Bought this for my 300blk build. All the hype is true. Of all the bcg I've had. This one was the best. She runs flawlessly. Very easy to clean. Best upgrade I done.Ordered another for my current 556 build.If you thought about buying one. Just get it. You'll be happy you did.

In use for 300blk. Hands the high pressure very well. The best part about these bolts are the balanced/widened tails they have that give it a smoother and faster reciprocation. The tapered ejector locks well with the barrel and strips the cartridges smoothly. Iv never had an issue with this purchase.

Finally put this in one of my ar’s to give it a shot at the range, I had a lot of issues with the gun once dropping this bcg in. The worst part of it was the shell casings just dribbling out of the ejection port. I swapped a few buffers into the ar with no change. Didn’t matter if it was suppressed or unsupressed, I still had the same issues. The coating on this bcg is awesome. That’s about the only positive thing about it.
