Using a cut-away gun and the important variants, Bob shows you everything you need to know about getting them apart and back together again, and understanding the changes along the way and why they were made. The weaknesses of the versions, and their strengths, are shown and explained as only the Master can. If you want the quick course on how to maintain these guns, and operating as intended, then this course is for you (if you want the long course, look into the basic 108 hour Professional Gunsmith course). 135 minutes.
