I have store credit and need some sort of riser/aimpoint mount solution for passive aiming that will most likely utilize the pictured riser and some C1 mount, limited to Badger stuff but that's okay as I like the few products I have by them. What height should I choose for the aimpoint? Where would I position this on pictured riser while still having room for my RAID or am I misunderstanding the point of this riser rail?
