For serious extended-range shotgunners, the Model SP-10™ is the ultimate in lethality – from duck blinds to the turkey woods and everywhere in between. Its 3 1/2" 10-gauge payloads are significantly superior in patterning efficiency to 12-gauge 3 1/2" guns, and even produce less felt recoil. It features a corrosion-resistant gas-operated action in which a small cylinder – not the entire piston – moves, helping dampen rearward force. Ultra-reliable and smooth, it’s the only shotgun worthy of the ultimate bird-leveling payload. Ducks and geese beware: The big gun is now available with the state-of-the-art wetlands concealment – new Mossy Oak® Duck Blind™ camouflage. The Model SP-10™ Waterfowl features a 26" Rem™ Choke barrel with a high-visibility fiber-optic sight system, and comes with a full set of three Briley extended specialized waterfowl choke tubes.
