Actually, a friend and I were considering getting into gunsmithing. He's already very good at it and I'm learning. From what I understand, an FFL is required to sell your services as a gunsmith.
My storefront would be my garage/shop for now, possibly something else later. I understand that there's a form that needs to be filled out and approved before that happens though.
I want to learn to build firearms. Not just buying a kit and assembling one... actually building them. I have no interest in selling firearms for a living but I wouldn't be opposed to the idea eventually.
I like learning how things work. I like to tinker. I'd like to build things like a supressor just to see if I could and to see if I could "build a better mouse-trap". From what I understand, that requires a manufacturers (Type 07, I believe) FFL but it still leaves me wondering if I would be able to purchase a rifle from John Doe in Texas and have him send it to me on my FFL. Does the manufacturers FFL allow me to deal in firearms as well or is an additional license required on top of the Type 01? I expect I'll get a lot of those questions answered when the regulations arrive... but the more information I find online, the more questions I seem to have.
