What’s Included
- Mossberg Model 500 12 Gauge pump-action shotgun
- Receiver filler screws installed in factory drill-and-tap holes
The 18.5 inch steel barrel uses a fixed cylinder bore and a plain muzzle, paired with a single brass-bead front sight for fast alignment. This configuration is straightforward and well-suited to a wide range of 12 gauge loads within its fixed choke parameters.
Its receiver is an anodized aluminum alloy finished in matte black, with anti-glare serrations across the top. The receiver is drilled and tapped at the factory and fitted with flush filler screws, offering a clean, unobtrusive top surface as configured.
The synthetic furniture is finished in black and includes a straight-comb stock with molded texturing for grip and a ventilated recoil pad. A rear sling swivel stud is installed at the stock toe. Length of pull is 14.0 inches, providing a consistent shoulder fit.
The pump-action system feeds from an under-barrel tubular magazine with a stated capacity of 6+1. The action is controlled by Mossberg’s ambidextrous top-tang safety, and the matte black finish across metal and furniture helps reduce glare.
