I posted this in the general area first--maybe it would be better here. Being a nuts-and-bolts kind of person, I would like to get to know firearms on a more technical level. Does anyone know of any gunsmithing courses (even non-degree classes) for offer in the Phoenix Valley area? If not, how about any shops willing to take on part-time apprentices? Appreciate it--I've already learned much just by reading posts here for a couple weeks.
