UNW .43 & .50 Cal Barrel Plug

This is a barrel plug that can be used for a .50cal and even a .43call marker. when you use a elastic cord of a length of 40cm. Than it will work for both the Umarex T4E PPQ and HDR 50. But it can be used for different type of markers as well. I made this to provide a way to make these markers a bit saver when you are out of the game
area. Like we are used to with other markers.
