Just got my PTG bolt head (LH, LA, .308) after a two month wait. Very well machined. Except... the lugs are 60 thousands too long front to back. So it won't close.

IIRC, .560 vs. the correct .500.

I'm new at this: Can I correct this by screwing the barrel out, and re-headspacing? Or do I need to return the head to PTG?

Thanks.
