I have installed a Leupold Vari-X II 3-9X 40 MM scope on my Ruger Model 77 Stainless in .30-06 without lapping the rings and got good results. I just purchased a Ruger NRA Model Mini 14 and I'm going to go with another Leupold VX II 3-9X 40 MM on it. I'm giving serious thought to lapping the rings because Ruger rings lend themselves to misalingment because of the way they are machined into the reciever itself. Has anyone done this? I'm just wondering how labor intensive it is? I have a 1" Brass rod to use as a mandrel, and I turned a couple of points out of 1" Brass as well. I know the .223 doesn't have much in the way of recoil, but lapping can help take some of the stress out of the scope if there is any misalingment. Also, can anyone tell me the correct torque for Ruger Rings when mounting to the receiver, and the scope rings themselves? Thanks in advance,  Bill T.

I have a Ruger M77 MkII in 300 wm, I did not lap the rings, and have had absolutely no problems at all with them, they are pretty easy to align, the only thing to watch for is the elevation from one to the other, use your drift to verify the alignment and if necessary lap them or get another set should they be too far out.

I haven't put the rings on but they appear to be identical, and the receiver has a different elevation for the front and back. I really wish Ruger would mak a steel Picitinny Rail that would mount up to the Ruger receiver lugs.  Bill T.

That shouldn't be right there, that's got to be a goof up. They should be of differing heights, as you have stated the receiver is different front and back. You can purchase a rail for a Ruger, although it The receiver that is will need to be tapped

Cyborg,
 
something doesn't seem right, but according to the Ruger website they shipped the correct rings.
 
 
My gun is a Mini 14 NRA Ranch Rifle. If I enter that data under "Family", and under "Model" enter "blued NRA M-14", it says in red the gun ships with 2, "5B" rings, which is what I have. As near as I can tell they are both the same height with the lug on the bottom in the same position. Perhaps the lugs on the receiver are the same height because all of the rings they show are identical for both front and rear applications. I'm getting at that age where I "confuse" easily!  Whacko  Bill T.

Well maybe they are the same height, I'd surely verify first though, that's for sure. I hope this all works out well for you Bill. Keep us posted sir, if you don't mind.

Will do. I'll check center to center with some 1" pointers I turned up at work before I lay a scope in them.  Bill T.

The scope is mounted, and she's ready for the range! It's a Bushnell Trophy 3-9X 40 MM with Mil-Dot Reticle. The rings Ruger shipped with the rifle worked out very well. Just high enough so I can get the lens cover on the front objective. I checked with a set of points and the rings lined up perfectly. I even got the crosshairs straight the first time! A first for me. Tomorrow, weather permitting,  we'll see how she prints.  Bill T.
