|Many hunters and shooters like to work on their own firearms, and the American Gunsmithing Institute has a comprehensive list of courses on DVDs that make it much easier to work on almost any kind of firearm at home.
AGI, located in Napa, California, has a new Technical Manual & Armorer's Course on the Winchester Models 1892, 1886 and 71 Rifles.
Hosted by Master Gunsmith and Certified Gunsmithing Instructor Bob Dunlap, this DVD unveils the mysteries of these John M. Browning classics.
A cutaway gun and AGI's extreme close-up video is used so that the viewer can actually see how all of the systems work and how the parts interact.
Among the items covered are:
• Discussion of the basic similarity of all of these Browning designs, including the later Model 71 in .348 Winchester
• Discussion of the improvements in this design over the earlier B. Tyler Henry designed Henry, 1866, 1873, and 1876 Winchesters
