We have all found ourselves in a situation where we are getting ready for the big hunting trip, when all of a sudden we can't find our Shotgun Magazine Plug. Luckily Remington made some spares! This factory original shotgun magazine capacity reducing plug is designed to fill the empty space in the tube. The plug, when installed properly will reduce the capacity of your shotgun in order to bring it into compliance for hunting. This is the same factory part that shipped with your original Remington shotgun.
