Well I hadn't either , till a customer brought me one . Now I have , I went over it with a fine toothed comb , to figure out what happened to it . That forend is steel lined for a reason , makes the gas come out the top when it can't cycle the action because there's a piece of brass stuck in a rusty chamber . I spent an hour cleaning the rust out of the chamber and polishing it up , I've seen some nasty ones , but none this bad , I'm surprised it would even chamber a round and fire . The thing runs like a Swiss watch now , just needs a new forend !
