You also can try a comb riser. I have a leather lace-on comb riser on one 99 and you get used to its looks. Cabalas used to sell one that for all pratical purposes looked just like something you could have bought at a hardware store or sporting goods house back in 40s and 50s.
I have done this on a couple, and it works good. The leather lace on type.
They also help on the European style stocks that are on many BRNO, CZ, etc... when using scope.
