The Winchester SX4 Compact 12 gauge semi-auto shotgun (Winchester part no. 511230392) is built around a shortened, 13-inch length-of-pull stock that makes it a natural fit for smaller-stature shooters, youth hunters, or anyone who wants a trimmer-fitting gas gun. Winchester built the SX4 around its Active Valve gas system, which self-regulates for a wide range of loads and keeps the gun cycling reliably from light target loads to heavy waterfowl and turkey shells. A 28-inch chrome-plated barrel and matte black aluminum alloy receiver keep the SX4 Compact durable and easy to maintain in the field, while a TruGlo fiber-optic front sight speeds up target acquisition on moving game or clays. Three included Invector-Plus choke tubes let you tailor the pattern for skeet, upland birds, or waterfowl without buying chokes separately.
