Marlin Lever Action Rifles - 1894 & 336
- Marlin Lever Action Rifles Models 1894, 1895, 444, and 336
Bob Dunlap understands the design, function, and repair of James Marlins classic lever gun design as well or better than any other gunsmith alive does today. All of these rifles are essentially the same mechanically. The only difference between the pistol caliber 94s and the other guns is the fact that their bolts are square and the right side of the action is open all the way to its rear. They are operationally identical as well and disassemble the same way. Bob uses a cut-away gun to enable you to actually see how the internal parts work together, and their function. If you want the quick course on how to get the Marlin half of the two best-selling rifles in America , the other half being the Model 92 and 94 Winchesters, 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.)Among the items covered are:
