I have no idea what's going on. I just bought a Mini for my son and the first trip out the bolt keeps sticking foreward and it'll leak really bad. I've taken it apart and replaced orings. I can't see anything wrong. Any advise would be greatly appreciated. I haven't had a single problem out of mine (knock on wood) yet. We are nOOb's but I can read instructions and trouble shooting sections and no luck. I guess I can call Kee Action and see what they say. I like asking the forum for input first. Thanks. It is lubed up properly as well.
