All I polished was all sides of the rails, the extractor & the spring guide. I started with 400 grit paper, 800, 1000, 1500, 2000 then mothers polish with cordless dremile.
New guy here. Well almost new. I recently picked up another 15-22 the other day (had one in the past but sold it). Question is is there anything to gain on these rifles if the bolt,rails & ejected are polished? I did everything on my 10/22 & it made big difference, a lot quieter & smoother.
