If you don't know what the spec is how can you say the bolt is out of spec? I can't believe they didn't look it up.
If the bolt lugs measure .280" and it does not lock in the barrel extension because there isn't enough room it seems to me the barrel extension or the thread shank on the barrel is out of spec.
The barrel shank should be .620"
The depth to the back of barrel extension lugs .907 +-.001(face of extension -front face of extension lugs)
max bolt lug length .280.
All of that should leave .006-.008" clearance between the front of bolt lugs and breech.

The 6.8 is the best choice for hunting deer and hogs with an AR15.
