Originally purchased with Weaver Kaspa 3-9x40 scope. The rings will suffice for the Crossfire but the mounting base plates are at too great a distance from eachother. The front ring sits about 1/4" up on the just widening objective lens housing. Is there any solution without having to go for a 6.5" or so Picantinny rail? Seems lke this might be a common problem.
