Jim, you unscrew the magazine tube (hand pressure onl! Never use pliers or a wrench. As the tube unscrew the milled bolt that goes into the frame will be lifted above the frame. Now slide the forend back as in loading, pull the barrel and magazine tube free from the frame. You may have to fiddle with the slide steel a bit to remove the assembly. Goes back together in reverse. Hope this helps you out. It was one of the best pumpers ever designed in the days before guns were punched out like so many donuts. Chopper
