I am an experienced machinist with a home workshop/small machine shop. I have made a several parts for myself with my Lathe, Milling machine, etc, such as scope mounts, muzzle brakes, etc. I guess the parts I made are considered assesories and not firearm parts. I am planning on starting a small business with my machine shop/workshop, and I plan on running everything by the book as a registered small business because I already have work lined up for my mill & lathe that is for a few tool & die shops because I wanted to be sure I had work before I get started with my business.
Although I will be manufacturing a few items that are for the automotive industry, I would like to manufacture a few firearm assesories like scope mounts, muzzle brakes/flash suppressors, and tactical rails for various firearms. I also would like to cut (keeping firearm barrel lengths legal of course) crown, and thread the muzzle of a barrel (to attach a muzzle brake). I know if you manufactured actual firearms or receivers, then a special firearms related permit is required. However if I was to manufacture assesories like muzzle brakes, scope mounts, etc, I thought that all I need is just my small business license in order to sell these parts.
So basically my question is if I have a registered small business, do I need any other permits/licenses to manufacture and sell firearm assesories, and cut/crown/thread the muzzle of a barrel (to the legal length) ???
