Took my A400 to the skeet range today and shot a few rounds. Everything was good and great firing and mechanics wise. Came home to take it apart to clean it, dropped the trigger assembly and a few parts flew off. Needing to know what parts are what and if anyone has any ideas on how to re-assemble them. Trigger will not release and shell carrier is not holding tension. There are parts on these that at missing and I believe I have rounded them up from the floor just need help assembling it again. Here is a picture to show what I have any experts tell me if I am missing something as I will continue to look.
