yeah like i said it isn't my bp gun...I just tried to help the guy out to try and get the plug out...it's a cva 50cal apollo or something like that. I believe he bought it at walley world....I told him he would problably have to take it to a gun smith. I told him that he needs to clean it after use so this wont happen again. I don't think he even put grease on it. Thanks fer the help guys...
