    My nephews 1187 was in a fire . He took it to a LGS to have it looked over and cleaned . This was 2 years ago . He hunted with it last season a few times and as you can see he didn’t clean or take very good care of his stuff . Everything is disposable to him , if it doesn’t work get a new one . I don’t understand this , because he is a mechanic and can fix things , if he wants to .

    We were hunting last week and again this past Sunday and his gun wasn’t ejecting the shells . A couple of times you couldn’t even hardly pull the bolt open . I told him to give it to me and I would look at it before you buy another gun . I was disgusted when I disassembled it .

    Now my question , without having a manual are the gas rings installed correctly for a 20 gauge 1187 ? I don’t think they are . 41AD25EE-CEBF-4081-998E-435D61F27E67.jpeg

    No. The one on the right in the picture should be flipped around and fit down into the ring on the left.

    My 11-87 12 gauge does not have that ring between the cone ring and the o-ring, but the first two on the left is the right orientation.

    The 20ga is different and I don’t see any showing it on YouTube .

    yes, this is correct, the tapered cone piece should fit into the larger piston piece. The flat side of the piston pushes against the action sleeve to move the bolt. 20GA has that extra piece between the piston and the o-ring, some type of seal I think.

    You do not need the gas seal activator , and shouldn't use it, with high power and magnum loads.
