I will be sending my bolt and trigger housing to Ohio for the Appachee Trigger kit. He takes apart the bolt and polishes the firing pin and striker. From what I have read the bolt is easy to take apart and a BEAR to reassemble. He has made a tool, jig, for the job. I have one of his kits in the Savage MKII and its GREAT. The Savage kit drops right in and costs 58$ (tax and shipping is included) The kit for the Marlin is $38. Flat rate USPS (small box is $5.80 + plus $200 insurance for $4.10) For the $38 he pays shipping and Insurance back to you. The Savage is breaking at 11 Oz. and breaks like glass and with no over travel or wobble. He guarentees pull under 16 oz with the adjustability back up if you want. It goes out tomorrow.
