Mine was an AA bolt also. No other problems with it.
On a side note (and I've posted about it before): One other issue does seem to crop up with the Grendel extractors, and that's their being too sharp. I've had a number of them in builds for friends that needed filed to work properly. The problem has always been that when they cut the extraction groove (forming the lip) they leave the edges sharp. Too sharp (somewhat burred). They grab the brass too well and don't want to let go. You end up having failures to eject because the brass hung on the extractor too long. I just hit them with a jewelers file and the problem goes away. I haven't ordered any bolts from AA in a while though, so I don't know if it's still an occasional issue or not. Just figured I'd toss that in-- in case anyone else has that issue.
