I don't think this is accurate.
Not long ago there was a thread here where a guy was having similar problems with an LBC bolt. I want to say he tried 2 more with the same sheered lug results. I believe he recently posted that he got an AA hard use bolt and the weapon is operating fine suppressed.
It was hypothesized in that thread that LBC was using 8620 for their bolts. I suspect that's what happened here.
