Questions & Answers
I have a Ruger MK 2 M77 30-06. I am putting on a 44 lens and 30mm tube sized scope. What rings do I need? Expert Answer

This Ruger Scope Ring will only accommodate a 42mm objective lens. I would recommend the Leupold Ruger Rifle Scope Mount Rings in a medium height, which can be found by using the link below:

what ring heights would i need for a ruger hawkeye .204 ruger (two different heights) scope is a vortex 30mm tube 44mm objective Expert Answer

Since this Ruger Scope Ring 4K30 Medium Stainless Steel 30mm 90285 fits up to 42mm objective lenses you will most likely need to go up a size. So you will need model 5B30 90274 for the front and model 6B30 90275 for the rear.

1 Scope Ring? by Bad service, October 1, 2021
You sent me one scope ring? What kind of idiot would sell a single scope ring? It’s useless! I am really not sure what else to say. I am sure these are great scope rings. I just wish you had sent me two.

Strikefire on ruger mini 30 by FLIP, Verified Owner, October 11, 2024
I took the cantilever mount off that came with the strike fire, because it was too high, and put this ruger scope mount on. It's a the right height and is very secure.

Ruger rings by MJ, June 21, 2023
Ordered two high Ruger rings for my m77 not realizing it took two different sizes so I returned one of the high rings for a medium ring. The process was really easy and actually received my medium height ring in a couple days
