Can anyone else comment on this?
This is my SIG516 upper with the bolt and carrier fully in battery. Note that the locking lugs are fully seated inside the barrel extension.

This is my PWS MK114 upper with the bolt and carrier fully in battery. The locking lugs are visible against their respective barrel extension lugs. My MK109 upper is the same way. I wonder if there's something off with the PWS bolt carrier cam slot that is keeping the bolts from fully rotating into battery.

Of course this all could be absolutely nothing to get worked up about but I notice that the locking lugs on my MK114 and MK109 bolts are starting to look somewhat battered.
I've looked at a number of AR's--both piston and DI--from other makers and haven't noticed this from other brands.
