| I am having a tough time getting a new NIKON bore sighted on my Rock River with a flat top rail. I have a Rock River scope mount for the rail with 1" rings. With the rifle in a padded vice I remove the bolt assembly and bore sight to a target on the wall about 15' away. Trouble is when I put the scope in the rings I can get the cross hairs no closer than about 4" above the bullseye as seen thru the bore. I know the scope sits above the bore about 2.5 - 3", but this would still not get me to hit the target at this close distance. Should I start out with a shim between the tube and the rear ring? If so, what makes good shim material. Thanks |
