I will start it off I guess You don't want to go too low as the eye piece will interfere with the hammer/thumb clearance.
You will almost always have some front sight in you view, particularly with low power scopes.
The Best mounting combination I have found for the Model 94AE is the Weaver base and Millett Angle Loc rings. The scope will not move under recoil and you have windage in the mount.
The holes in the receiver are purposely drilled to slightly favor a right hand shooter and to give a bit of clearance for ejecting the cartridge cae. This can give a left handed shooter a small problem. Nothing serious but windage in the mountis is nice.
This is the .307 with a Burris Short Mag 4x. Good scope with a stupid reticle.
Here is a .356 with K2 Weaver in Weaver rings.
Here is a 25-35 with a Weaver V-3 which is an ideal setup considering g the need to give the power change ring some clearance.
