This “Pumkin Puncher”, the M500-S-12, is designed to fit a Mossberg 500 12-gauge shotgun with an EQUAL LENGTH barrel to mag tube ratio, such as commonly found on the Mossberg 500 Persuader with a 20" barrel. Please see pics for reference. This device is not a barrel mount, it simply attaches to your take-down screw. All you’ll need is a Phillips screwdriver, we supply everything else for the install. Your Mossberg must have the new style take-down screw that is 1” in diameter by 3/8” thick with a threaded stud hole in the center. Please see pics for reference. This device has an OAL of 2.630" with a standoff length, measured from the face of the take-down screw to the ends of the tines, of 2.247". The major OD is 1.250". All dimensions are approximate. This device is machined from 6061 T6 aluminum and as such machining marks may be present on some items. It is anodized flat black and branded. A quick swipe with a black permanent ink pen will camouflage the etching if you so desire.
