Ok I have been setting up a 870 for hd shtf an just to blast for practice. So far I have added a ati talon collapsable stock with tri rail forarm sidesaddle aftermarket follower and ported choke an extended tube. Was wondering if there was anything that needed to b changed out for reliability or performance. Was thinking may b extended safety if it makes a noticeable difference and would like to find a good light that doesn't cost a arm and a leg. Thanks for any advice or suggestions.
