How do you remove the front sight from a 22 SMK XS19 Supergrade Air Rifle so that I can fit a suppressor?

Most air rifles have the front sight pressed on. Others have a small Allen screw that holds them in place. If it's pressed on then you can take a small block of wood and using a hammer you can budge it off. If it's an Allen screw then back off the screw and slide off the sight.
