For serious extended-range shotgunners, there's only one choice. The Model SP-10. Its 10-gauge bore produces significantly superior patterns and less felt recoil than any 12-gauge, 3 1/2" gun out there. And like all Remington shotguns, it excels in the most extreme hunting conditions. It features a corrosion-resistant system, in which the cylinder, not the piston, moves, helping dampen recoil. It's the only shotgun worthy of the ultimate 3-1/2" bird-leveling payload - the 10 gauge. The SP-10 magnum comes with a vent rib Rem choke barrel and twin bead sights and safety switch. Interchangeable full and modified Rem chokes are included. Mossy Oak Obsession finish. Rem Chokes. Fiber-optic sights. Thumbhole stock.
