Questions & Answers
Ruger 1 are the rings the same number? I need 2 rings extended to really get the scope rearward! Are they needed in equal in height for a Ruger 1?

My Ruger no 1 is a model 1B with a 26” barrel and a Quarter Rib in 25-06. Front and back rings are the same height. You can use a medium height Ruger extended ring on the front to move most 40 mm objective scopes far enough to the rear. The turret on all of my scopes are either against the rear scope ring or very close to it. Really need two extended rings for optimum clearance. The objective bell on many 40 mm scopes will contact the Quarter Rib before the scope is back far enough. That’s the issue I’m having with a Leupold Vari X111 in a 2 1/2 x 10 50 mm. Good luck on finding high offset/extended 1” rings if you need them.

I assume that this off set ring is for the front what back ring do I need to match, for a Ruger M77 rifle? Expert Answer

This will mount on either front or back mounting positions. If you are putting it on the front, you would need one step higher ring for the rear. if you are putting this on the rear mount, you would need one step lower ring for the front.

Usual great Ruger quality. The offset worked for a short scope mounted on a long action gun. Pricing and shipping time from Optics Planet were great also. I was happy to find these in stock, they are always hard to find.

Offset ring worked perfect for my Ruger No.1. Without the offset ring I couldnt get a good eye relief. With the Ruger offset ring it allowed my scope to easily be within acceptable eye relief range. They work great with the number ones.
