So I have a Marlin SBL 1895 45-70 all stainless rifle. It was made in 2018 when Remington was still around to make things as poor quality as possible. However, it is better finished than most I have seen. It's nowhere near as nice as the old JM Marlin rifles are like. I took out the bolt and internal bits and the edges could pass for razorblades. The outside isn’t bad but any moving parts could use some serious smoothing out.
My question is: What’s the easiest way to do this? Take it down to bits and start hitting the sharp parts with 500 to 1000 grit wet and dry? Or maybe put some sort of mild abrasive, like JB Bore Compound or something else more aggressive like JB Bore Bright on the bolt, block, etc, and run the action till my hand gets tired?
Interestingly enough, the trigger is really pretty nice and I have no intention of playing with the trigger/hammer/sear relationship. I’d just like it to run smoother
Any recommendation would be appreciated.
