Marlin lever-action – disassembly and tuning tutorial

Marlin 336 SS

This is my 2 part video tutorial to help with disassembly and tuning a Marlin 336 for a smooth lever action cycle and accuracy (accurizing).

This was filmed using a Marlin 336 SS in 30-30 Winchester.


I am not a qualified gunsmith – This video is some tips that I found useful, and my thoughts. If you decide to work on your rifle, research everything extensively! If you’re in doubt, talk to a gunsmith. Wear safety glasses to avoid eye damage from springs. Remember you’re mostly just polishing, you should not be removing much metal at all. (especially avoid touching the trigger mechanism).

Stay safe and happy shooting 🙂

    Now that I have it apart and fixed how do I put it back together? (Revelation 200)

    • Hi Graham,

      I never filmed a reassembly video, but it has been requested often. I might film this video one day, but in the meantime you just need to replace the parts in reverse order, there’s nothing particularly tricky about it. I’d say a very light lube with gun oil and try not to over-tighten the screws, and you’re set.

    I like your Marlin 30-30 dissambly video. Do you have a reassembly video?
