The Mark 5 Conventional Stock features our spacer system which come with one 1/2 spacers and one 1/4 spacer included which adjusts the length of pull from 13 1/2″ to 13 3/4″ . You can lengthen your stock by simply adding new spacers and longer screws. NOTE- The 1100 and 11-87 shotguns can not be shortened shorter than 13 1/2 inches because of the recoil spring tube that protrudes form the back of the receiver.
Mine has plenty of room for the action tube nut and doesn't require any spacers.
