if you pay a gunsmith for an examination, tests, or a machine shop for the test, either way, you're gonna be paying someone, for something.
you can always include that in a reimbursement request from S/A.
it can go a long way to prove what is wrong.
as a former auto mechanic in my earlier years for about 17 of those early years, and otherwise, as a newbie of only 2.3 years myself, in the sport of shooting, and what "gunsmithing" i have done myself, and soon to start reloading, i got nothing else
you really "do seem and sound" combative, and as a person over 70+ myself, i will not longer tolerate your attitude or BS, when ANYONE HERE is trying to be helpful towards you
you got some really good God damned people here, and all you can do is be combative.
good luck, i really do wish you all the best.
i am out.
