Oh boy the infamous raid from 4yrs ago. still being brought up..
Might be 4 years ago, but unless the company has changed hands (I don't know one way or the other) that's kinda indicative of business practices.
I don't know too many illegals (even legals under 30) who can read mic's & calipers & prints, much less tell if what's coming off a machine is good or bad.
And that comes from direct experience in a precision industry not gun related, with who we can hire today.
YMMV
