When it’s a FTF, it’s a matter of the round failing to get fully into position. That’s the less frequent of the two issues. With the failure to go into battery, the bolt engages just enough to lock, but the firing pin does not hit the primer. And it literally takes a whack with a rubber mallet to disengage the bolt. And the bolt does pass when checked with GO and NO-GO gauges. Weird.

Did you tell them that( about the mallet)? The go -no go tests the head space of the face of the bolt, to the chamber. The tabs on the bolt, fitting into the receiver is something else. Sounds like the bolt is not fitting into the receiver properly. Combine that with the FTF, I'd suspect a bolt/receiver mate up issue.
