I have an adult butt stock, standard pistol grip, that came with a plastic butt plate. I would like to cut it to the length that it would be if it had come with a recoil pad. Then, leave off the butt plate and install a Limbsaver slip-on. Will this work? Do I need to have the butt plate on it? I can grind or file that down and then add the slip-on Limbsaver. Wha'da'ya think???
