Can someone tell me the order in which the rubber O ring is placed on the magazine tube when reassembling the 1187 12GA? I’m not sure if it’s; last, first, or in between when putting everything back on the tube. Unfortunately the Remington Schematic doesn’t show the order and the owner brought me the gun disassembled.
Action bar with inertia sleeve first (I know you know that) then the piston assembly, then the “o” ring, then the barrel, then the gas cylinder collar goes on the barrel lug, then the forearm, etc.
