Need help mounting new scope to Rugger M77 mkII

Hey guys,

I bought a Ruger M77 mkII 7mm mag from my Uncle last year. He let me borrow the scope that was on it to get me through deer season. I got a new scope for it (Leupold VXII 4-12x40)(old scope VXII 3-9x40). The new scope contacts the barrel in the front.

Now, the Rugger M77 mkII has unique rings that mount directly to the action. I'm assuming the rings on there now are "medium" height? Does anyone know how to confirm this? I found new "high" rings through CTD, but I don't want to order until I'm sure they will work. Thanks

My buddy has this rifle with a vortex viper with a 50mm bell. He runs a high in he front and an extra high in the back. I would think with a 40mm you could get by with a medium in the front and a high in the back.

It depends on the brand you use. Leupold "low" seems to be lower than Ruger "low". Leupold "low" did not fit on my M77 with the 3x9x40 VX-II. I would go with at least medium.

CO Shooter-Does he get away from a 20 MOA rail by using the 2 different size rings?

If that works, that is a smart idea. I am having the same problem and running out of elevation.

Call Ruger Customer Service. They are very helpful. I had a similar question last year about my old model M 77. They told me exactly what I needed for the particular scope application that I was contemplating and gave me the part #.

I had a similar problem with my Mod. 77 MK II. I called Ruger and they told me to send the rings back to them and they sent me the correct rings free of charge.

Sorry I call bullcrap...It is impossible. He would never get solid contact. 2 items of different heights with flat tops on a single plane will never match up properly and flat with a straight line connecting them.

Why do you think they make raised and angled bases instead of people just using 2 different height rings.....
