I bought a 12g Auto-5 for a fun project and noticed 2 things, it has a little rattle (sounds like a door or flap that may be normal), is this normal? My 20g is at our other house so I wont have it until next week --

Second thing, isn't the bolt supposed to lock back when you open it (on an empty chamber)? If the trigger is pulled and the bolt is closed and I press the bolt release button you can hear something give and then it will let me lock the bolt back but from what I remember the bolt should lock back on an empty chamber
