Marlin 39 & 39A Lever Action .22 Rifles


Marlin 39 & 39A Lever Action Rifles

For over 110 years boys have been filling their dreams with Marlin's little lever action .22 rifle and its successors.  These are the world's most popular .22 lever actions and there are millions of them around. 

The Golden model 39A started life as the Marlin model 1891, the first lever action rifle ever chambered in .22LR. The tubular magazine was changed to front-loading with the model 1892. The 1892 gave way to the takedown model 1897, which became the model 39 in 1921 and model 39A in 1937. The Golden model 39A Mountie was introduced in 1954. The 39 was produced until 1983 when the current Golden 39A with the cross bolt safety was introduced. Changes between models were so minimal the rifle is considered to have been continually produced to the same basic specifications for over 110 years.

Until now there just was not any information available to the average owner on how to care for and improve these guns.  Instructor Bob Dunlap shows everyone how to completely strip the gun down, put it back together, and what to look for in the process. Bob understands the design, function, and repair of James Marlins classic lever gun design as well or better than any other gunsmith alive does today. He uses a cut-a way gun to enable you to actually see how the internal parts work together, and their functional interrelationships. Now you can learn what each part is supposed to do, and how this great design has been the basis of one of the most successful guns ever made.

If you want the quick course on how to get the best-selling lever action .22 in history 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.) Get a copy of this course now, you will be glad you did.

Among the items covered are:


  • Discussion of the commonalities between the Marlin lever guns, whether they are the smaller rim fire, the medium size pistol cartridge center fire, or the full size rifle caliber center fire guns.
  • Interesting magazine tube arrangement on an original 97 is shown
  • Why the cartridge stop (that really is not) was done away with in the 1983 redesign
  • Guns are extremely accurate and robust, they rarely break
  • Many of these guns that are almost a century old are still in use today
  • Designed by James Marlin, they share some very clever and innovative design flourishes with the Marlin centerfires.

  • What locks the bolt in place, what the lever pushes against that actually retracts the bolt

If you noticed how often the terms "explanation" and "visual demonstration" are used, you may be getting some idea of why this course is necessary for any Marlin 39/39A rim fire lever gun owner, or someone who intends to be.
