Well, being a gunsmithing student, I couldn't just leave the gunsmithing topic empty. For anyone here who may be interested in gunsmithing for personal projects or as a profession but don't know how to learn without having to go to a college, which is sub-par most of the time with few exceptions anyway, I can suggest from personal experience, taking courses from the American Gunsmithing Institute. They are a great group of people with absolutely top notch instructors, including Master Gunsmith Robert "Bob" Dunlap. They also have good courses covering machine shop and welding, which are both obviously very applicable skills to a gunsmith. If you want to learn from the best, they are the place to go, check them out.
