There are a few different ways to install a choke tube on a shotgun. One way is to remove the barrel from the gun and then screw the choke tube into the end of the barrel. Another way is to use an adapter that screws into the end of the barrel and then the choke tube slides onto the adapter.
Whichever way you choose, make sure that you tighten down the choke tube securely so that it does not come loose while shooting. Also, make sure that you do not over-tighten it, as this can damage the threads on either the barrel or choke tube.
