Bob Dunlap completely understands the design, function, and repair of Eugene Stoner's masterpiece, the AR-15 rifle. This extremely successful design, whether you love it or hate it, has been the U.S. military's first line battle rifle longer than any other in our history, over 40 years as of this writing. It is the second most prevalent rifle design in the world today, behind only the AK-47 and its derivatives. If you want the quick course on how to get this 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).
The American Gunsmithing Institute (AGI) exists to provide firearms enthusiasts with the knowledge needed to keep their guns in safe and top-notch condition through our extensive line of comprehensive "How-To" videos courses on Disassembly/ Reassembly, Gunsmithing and Repair for many types of rifles, shotguns, and handguns.
