    I purchased an 870 competition project gun a while back. I am getting ready to start working on it and have noticed that the piston ring is missing. Can somebody give me the dimensions of this ring (inner/outer diametrs and width)and if possible tell me what material it is made from. Any help would be greatly appreciated. Thanks, Joe S.
