Noremf,The scope mount you have is a great mount but it was designed to be used on an AR type weapon-a flattop receiver mount.
You would be better served using a set of scope rings for a Weaver/Picatinny style. A medium height set of quality rings should work fine.
I personally prefer Burris Signature Zee rings,but there are plenty others that would fit your needs. You can get the scope down close to the barrel using a set of rings,instead of using a scope mount on top of a base rail.
