RE: CVA Bobcat project
i like to use a brass punch and a a small 3lb. lump hammer to get the old sights out. i use electrical tape around the area im gonna whack just in case of a miss or the pounch slides off and down the side of the barrel.when you tap the new sight in be careful and tape off the new sight and any areas that might get scratched from the punch missing or sliding off. to give the dovetail cut on the barrel a tighter fit to your new sight you can use a ball pein hammer on the round side to just lightly tap the edges of the dovetail to close them up a hair. this will make the new sight sit tight. for cold blueing i would use the oxpho blue from brownells.
