I am looking for a base that converts the Ruger to 1913 rail.

What I really would like is a direct mount (saddle mount) like on the Sako TRG.

The rifle is a long action M77R getting a new fat barrel in 9.3x64.

My math works out that I need about 20 MOA I don't have in the Ruger system.

This worked on my rifle.

Burris makes adapters to convert to a Weaver base. Then I used Burris signature rings with offset inserts to get 20moa elevation correction.

Try or start with the next shorter ring height than you would normally use as the adapter bases add some height.

Option 2 is to have is drilled for flat bottom bases and get a flat 20moa rail for it.

I really wish that Burris made ruger mount signature rings, but no dice.

I might ask someone like Spuhr to build me a saddle mount for a Ruger LA.
