I was going to go with a LLC but my FFL ended up going too quickly. So after a year or so as a Sole Proprietorship, I'm going to switch. A house/property/polebarn purchase is in the future so I will need to redo my FFL anyway. But in the meantime I am really small time, just doing friends, church members, and maybe some boyscout, and local groups for business. I sell ammo/acessories, do light gunsmithing/cleanings, and sell hand guns of course. I am currently buying Mosins cleaning them up, functional checking them, and making a little profit, all the while, honing my gunsmithing skills.
