Iron Horse/Blackwater Sentry 12 (12 ga shotgun) Brand New

I have a brand new never fired Iron Horse/Blackwater Sentry 12 (12 ga shotgun). It's a mag fed AR style pump action shot gun. It comes with 2 5 round mags. This is a great gun but I haven't even had a chance to take it to the range yet.

Asking $700 OBO motivated to move this fast.
