I want to talk process and steps, not about brands and such. At least for now. The low down: I found an only late 1960’s Ruger 10/22 in my old mans closet and it was rusted and gunked up. I cleaned it all out nice and got it shooting again and decided to mount a scope on it. No it’s not a $50,000 scope and I don’t have laser guided precision nanobots to assist in the install. Here is what I did: The 10/22 had a little rail mount on the receiver as you would expect. When I put the scope on and tightened everything down I used a bore sight and at 25 yrds the laser dot was off center to the left by half way and to low by about half way as well, meaning essentially that the sight was aimed too high and too far to the right of the barrel. When I adjusted the L/R and elevation on the scope I essentially had to adjust in all the way in both directions to get the scope and bore sight centered. This however would be unacceptable because there is no more room for adjustment either to the right or to go up. So I took the scope off and adjusted the L/R and elevation to be in the middle of the dial so there was plenty of room for adjustment either way. I then used electrical tape and pretty much put that in the needed areas on the eyelets so when the scope rested in them the tape would force the scope to correct itself by cradling it when the eyelets were tightened down. Doing this I was able to get the bore sight and the scope to perfectly center … however I used a lot of tape and just doesn’t seem like the right way to go about it. So I assume that the best way to go about this would be to go to a gunsmith and have them center the rail better since it’s an old rifle and I’m sure it is off. Since I’m not going to do that, what is the best process for mounting a scope?
