Would like to hear input on this if anybody has firsthand background with 6.5G and the alleged bolt issue. I'm considering a custom-built 18" 6.5G upper, but see a lot of mixed reports of broken bolts in Grendel rifles. It's hard to get the straight story. Some say this is an Internet myth, some say it USED to be an issue now it's resolved, some say that it's inherent to trying to run the 6.5G on the AR15 (their argument is that because there's simply less material there, the bolt cannot be as durable). I talked to one of the leading precision builders of the 6.5G, and when I asked about it the owner said: "We've only had 6 broken bolts reported in the last year." He was saying that as a good thing. But I was doing the math in my head, say his business built even a couple hundred 6.5G uppers/rifles in the last year (they build a lot of other things as well, so they wouldn't be cranking out just Grendel uppers exclusively). Six broken bolts out of a couple hundred is too many, IMHO. You hop into discussions at other forums like the Hide, some say they've had multiple broken bolts, some say they never have broken a bolt. The impression I have gotten--which I admit could be wrong, and I actually hope I AM wrong because I want to get this upper--is that the folks that run their 6.5G rifles hard and shoot a lot, do eventually get broken bolts regardless of the bolt's reported quality or who the builder was.
The problem is I don't have much to go on besides the above. If anybody has more that can either confirm this issue or put the myth to rest, would like to hear it.
