I was just checking around the internet for one of the shotties, as I've already got the fullsize M1100 and a pistol grip M870, I certainly would be interested in getting a hold of yours. However, I am wary of how much damage has been done to your extractor. The o-rings I use on my shells are #7's (1/2" Outer Diameter x 3/8" Inner Diameter x 1/16", a real nuisance to get on but they work perfectly until they get worn away.) I suppose I can start my bid at $180 and we can go from there, and if you do get a pack of o-rings and test with them that would be awesome, and if not a picture of the chamber would rock. Thanks.
