Aimpoint 9000SC rings

Have an Aimpoint 9000SC and want to mount it on a Henry, pump, .22WMR. The rifle comes through with a built-in 3/8" rail. The SC is a 30mm tube. Medium rings are not tall enough to raise the sight above the stock rear sight. Need either "high" or see-through rings in 30mm, 3/8" to get above the buckhorn rear sight. Can anyone help me out? Have not been able to find that combo. Thanks....

These RGPM-30H4 Leapers rings may be just what you need.
