brings up a good point. I never bought the tool, but I made my own version of it after removing the retaining nut with just a screw driver and having it fly across the room. I welded a flatplate to the end of a bolt to act as a screwdriver blade, cut a notch into the center of the plate for a section of sectioned cleaning rod to go through the retainer bolt and stick up a little bit. The correct tool has the rod connected to the tool to make removal safer but its getting that long spring back inside the recoil tube thats the tricky part. The rod holds the spring straight and makes it a snap to get together. Wear some safety goggles and don't take one out around some new wine glasses your wife just bought like I did.
