Disassembled the thing and lubed it up and then realized I had next to no idea how it fits back together. I could very possible figure it out if I had enough time with it, but really I don't so I'd like to fine someone who knows what they're looking at to put it back together so no one gets killed when we go out to shoot it. It's a standard 12 gauge pump made by High Standard. I am willing to pay, feel free to send me a PM, thanks.
