Bob Dunlap takes you through the history, design, function, and repair of Bill Ruger®s immensely popular .22 semi-auto. The 10/22®, along with the 1911 pistol and the AR-15 rifle, are the most accessorized firearms in the world. Bob uses a cut-away gun to allow you to see the operation and interaction of all of those hidden parts. If you want the quick course on how to get the Worlds Most Popular Rim fire Rifle apart, back together, and operating as intended, then this course is for you (if you want the “long course,” look into our basic 108 hour Professional Gunsmith Course.)
