This is a magazine plug Winchester 1873 and 1892 .25, .20 and .32, .20 caliber lever action. This plug has the lip which fits into the slot on the underside of the barrel. This plug fits into the barrel Forearm of the magazine tube. Remember when you remove the screw to take the plug out there is a lot of tension on the plug from the magazine spring.. It will shoot across the room or take an eye out if you do not hold on to it!
