Why not use one of those stick on comb pad thingys?
I use a Beartooth Comb Riser when I need to. Is pretty much the same thing only slips on and has shims that allow for different heights.
"An archer sees how far he can be from a target and still hit it, a bowhunter sees how close he can get before he shoots." It is certainly easy to use that same line of thinking with firearms. -- Unknown
