Gary, I'm gonna show my ignorance here, but couldn't you just use the included Ruger rings or just mount the rings to the rail directly on the rifle? I know that would remove your quick disconnect feature, but it would get the scope down lower? Which is more important scope height or quick removal? And you just said it is gonna be a slow burn rifle.
I am not going to speak for Gary but this is my thought. The GSR is a scout carbine so BUIS is a must. If you use the supplied rings then you loose the use of the rear BUIS. It would be nice to keep the BUIS and have a magnification too.
