I have always been curious about what it takes to become a gunsmith. Does it even require licensing or certification? Is it "legal" to simply call yourself a gunsmith and start doing some work? I realize you are obviously limited to what you know, personally I would not be comfortable trying to refinish a stock. However, I could assemble and AR, mini 14, 10/22, a Remington 870 shotgun, and several handguns from loose pieces, blindfolded. Not that it makes me an expert on any of them but I would be confident to install trigger groups/components or re-barrel any of them given the right tools and equipment. I have seen a lot of stuff about PSU and other correspondence courses but would prefer an apprenticeship program of some sort. Anyone with experience feel free to chime-in.....
