The Winchester SXP Marine Defender shotgun in 20 gauge with an 18-inch barrel (brand part no. 512268695) is built for corrosion resistance in a lighter-recoiling gauge. Winchester plates the barrel, chamber, and bore of this Marine Defender in matte chrome over a satin-finish composite stock with textured grip panels. A drop-out trigger group and rotary bolt simplify cleaning, while a crossbolt safety and TruGlo fiber optic front sight round out the package.
