Synthetic stocks present some peculiar problems when cutting them off but it can be done. The molded areas where the buttplate screws thread into move be removed by the shortening process. There needs to be something added to screw the pad to. I usually add slice off an old wood stock that fits the remaining hole. This is epoxied into place and the pad is screwed to it as normal.. I've not used the limbsaver pads, I normally use Pachmeyer Decelerator pads. They work well and hold up over time.
