Does anyone have a manual for one of these? Or advice on what needs to be taken out to disassemble the gun? I've managed to get the seized/rusted trigger guard screws and security screws on the side of the forestock out. This is a salt gun that I'm attempting to take apart so I can clean the action and barrel. I'm trying to figure out if I need to find a way to remove the butt stock screws and/or the sling mount screw as well to fully take it down. Any advice would be greatly appreciated!
