removing rear adjustable sight from Ruger mrk2
I read in the forum what it takes to remove the rear adjustable sight from the Mark2, but there was mentioned a "set screw" on the adjustable sight models, and to make sure you remove it before you go pounding away. I'm not sure how old this model is, but I don't see a set screw. Did all of the adjustable models have this screw? Any help would be great.
