Actually they are not one piece. The back portion is the plug which you need to push all the way into the back of the firing can using the eraser end of a pencil. The bolt stop then goes where the stock bolt stop goes in the front of the firing can, the only difference it has a smaller diamater opening for the bolt which has no tail.
