Remington 740 / 760 Rifles


Remington 740 / 760 Series Semi-Auto and Pump Rifles

Bob Dunlap understands the design, function, and repair of these extremely popular deer woods guns as well as anyone. These semi-auto and pump action guns are, with the exception of the force causing the action bars to move (hot gas or your hand), are practically identical. In fact, the trigger groups (as well as those on their 870 and 1100 shotguns) are identical. This course covers all of the models and variations of this series of rifles.

Using a cut-a way 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 our basic 108 hour Professional Gunsmith Course.)

  • Discussion of the origins of the guns in 1949, and the reason why they became an instant hit with hunters, particularly in the Midwest, Northeast, and South
