The newest addition to the NRA Gunsmithing Schools is at Flathead Valley Community College in Kalispell, Montana. This school is being ramrodded by Brandon Miller, who ran the NRA School for Murray State College in Oklahoma for a while. So, you have experienced management and the instructors are very experienced as well, with a wide variety of expertise.
Everything from Basic Gun Safety, to machine shop, glass bedding rifles, and classes on the 1911. Much more is listed in the brochure which you can download from the web site linked below.
These short term classes allow professionals to take a little time off from business to expand their abilities, or for the hobbyist its a great way to learn the specifics your interested in. Either way its a convenient way to learn with classes normally running for 5 days or less.
Check out the list of Classes being offered at FVCC this summer at this link. I just talked to the staff at the college, and as of today there is still room in many of the classes. Take a vacation and have some fun.
