From Thunder Ranch’s Facebook page:
I like this one because the Mossberg team approached Heidi and I and asked what WE wanted for ourselves personally and to design for all of you…it has an ambi safety that a Remington does not…a short stock thats good for all and we like the price…less then $400.
I know squat about shotguns so don’t ask me what model is it, but that one right there sure looks pretty. And if Mossberg keeps the $400 price, they will make a killing.
Update: Possibly Mossberg 590a with Sidesaddle, bead sight, rails and breaching device.
