A friend of mine has taken lots of classes there over the past 10 years.
He would go up for a week or two and take classes some 2 or 3 day some a week long etc.. He said it is a very good gunsmithing program.
One time he took my 10-22 up there and put a Hogue stock, Hogue heavy barrel and did a trigger jog on it. Took the trigger pull from the stock 4 1/4 lbs to about 2 1/2.
Another time he toom my Winchester Model 70 .257 Roberts and re-blued it when he took a Bluing class. Very nice job on both projects.
He also made all his own tools in a class once and built a 25-06.
