Been having trouble getting comfortable eye alignment on new Sauer 202 XT and tried Tom D's suggestion of using sugru (a plasticine which cures hard when removed from packaging). I wanted it as a permanent raiser though (rather than just for a stock mould) so employed a velcro strip (to allow room for bolt removal). I think its going to work. You need to use industrial strength velcro but the sugru is only £12 and very comfortable.
