Geerhed and Saguaro,
I gather your question is whether a fixed (non-Para) stock can be shortened?
Short answer: Yes
Long answer : yes, not by much, but maybe that's all you need.
The theory is to look at the tolerances and reduce them in the non-critical areas. Do NOT try shortening the rat tail, or springs. Where mods to a Para stock can be done with a saw, the fixed stock should be worked with a file or sander. Careful fitting of the buttpad (converting to a plate) and finessing the recoil nut (and tube) is where you can gain the greatest reduction. Eventually, you may find it possible to remove 1/2 to 5/8 inch from the LOP and that may be enough to make the rifle easier to handle.
The Izzy wood stock is the best starting point, though I've been able to get a Century down to the same LOP, as well.
Finally, if you are in any way NOT qualified, do not try this at home. See your gunsmith. As always, your mileage, and his, may vary (YMMV).
