Greetings, I have had a small shop in NW Ohio for 5 years now, just dealing in regular firearms, and accessories. We are now looking into getting our SOT, so we can start selling suppressors mainly, but possibly some full auto. Does anyone have any tips, or insight on what we should do? Is it just filling out another form, and paying the $500/yr annual SOT? I have 2 suppressors myself, in my personal name, and after using them on our range, I’ve had a lot of interest in selling suppressors... Thanks in advance.
