FX Indy scope rail

Hello. I purchased a Leapers scope for my new Indy. The scope rings that came with it are made to fit the bottom, wider slots on the rail, not the upper one. Problem is, the clamp isn't deep enough to get a good bite on the bottom rail slots because of the smaller one on top getting in the way. Do you guys mount the scope rings on the skinnier top rail instead of the bottom, wider rail? Thanks
 
In all likelihood the scope mounts that came with your scope are not meant for a dovetail rail. They are most likely picatinny mounts designed for a completely different rail system. A proper set of dovetail mounts for the Indy will only fit to the top dovetail groove. What appears to be the second set of grooves is only a cosmetic feature of that rail.
