I need to shorten my daughters 270 savage and put on a grindable limbsaver. I need some suggestions as to a specific product of an epoxy or glue that I can use to hold the screws that won't shatter or break and will adhere to the smooth surface on the inside of a synthetic stock. On another approach, would I be better off gluing in a piece of hard wood and then screwing into that? Any insights or thoughts would be greatly appreciated.
