Follow up... Wow got some action. I have been polite and explained the emphasis of non-detachable=none of the "assault pistol" features apply... I have received  4 phone calls from 2 separate clerks.  Well I can only speculate at this point, but no letter has gone out, but an explanation has been given.

I have been now inforrmed that my attachment ( clerk would not elaborate how) of the magazine has not passed the Majors inspection and although removal would destroy the receiver-, there is no mag catch to depress( I cut this off n after completely bottoming it out and attached a blind galvanized plate over it)

When I asked about the 80%...I was informed the LT n Kona Clerk were in error...training will take place. 80% and self manufacture is OK.

As to my firearm...I asked if I could address the Majors concerns regarding the attachment-fix it? Nope. Deemed illegal. My weld not good enough. I am being given the chance to transfer out of state. Details to follow, but I need to speak with an FFL who would cooperate.
I'm done I think.
