To me it's unacceptable that on web sites and even barrels that there are no markings if a mfg uses a non-standard grendel bolt (or 7.62x39).
We know it happened with Satern, CSS, and LW barrels. Hopefully they are past it, but if the problem really was a barrel extension vendor changed dimensions, this would make me think that they did not check headspace with a reference bolt, just set it up in a jig and shipped.
