Are both ring on the same way ? ( screw to tighten )
If not do that .
If the rings are on the same ,many times if you turn 1 around it will move of impact ,i am not sure witch 1 to flip ( trial and error)
On some rings you can file on the claw that grabs the base to move POI. ,if not you may be able to remove some off 1 side of a base.
If I remember right 1 thou. on a ring = 1 inch at 100 yds
