JayCee's solution has the further advantage that you can put temporary spacers inside the slip-on to give even more pull, and they don't show on the outside. When you want to return the gun to original condition, you just pull the whole dingus off.
One caveat--you need to pull the whole dingus off every once in a while anyway and make sure it's dry under there, especially after hunting. Trapped water will play hell with your stock finish.
I like these pullovers because of the "convertability," and the fact that they are, as one of my crude hunting companions calls them, "butt condoms" in the scratch-and-dent world. As for esthetics (sp?), I leave that to the Shotgun Fashion Police, who will no doubt be by with their ticket book....
