BAMF

Good evening. I’m a mossberg guy. (Please refrain from the cabbage tossing) I’m a veteran, my boss/best friend is one of the highest honored members in the armed services. I want to get the man something he didn’t know existed. He has a Benelli M4, is there any adapter/way to run mini shells? Or does anyone sell a 6 point, pistol grip, AR style folding stock? Lol. Asking for a friend. v/r ~Benjamin
