The Winchester SX4 Waterfowl Hunter 12 Gauge in Realtree Max-7 is a full-camo autoloader built for the marsh, with a 26-inch barrel and a 3-1/2-inch chamber (Winchester part no. 511303291). Winchester built the SX4 on the self-adjusting Active Valve gas system, which manages felt recoil better than recoil-operated systems and pump models. The grip area has been redesigned for improved comfort and pointability, and an Inflex 2 recoil pad adds comfort on heavy waterfowl loads. Larger controls and a reversible crossbolt safety make the gun easy to run in gloves. It is a dedicated waterfowl gun with a full camo exterior to help you hide from cupped-up birds.

Key Specifications

• The gauge is 12, the standard waterfowl size for steel and heavy shot loads.
• The chamber is 3-1/2 inches, which handles 3-1/2-inch, 3-inch and 2-3/4-inch shells.
• The barrel measures 26 inches with a 1/4-inch ventilated rib, a length that points quickly in a blind.
• The magazine holds four 2-3/4-inch shells, a good capacity for a hunting autoloader.
• Overall length is 47 inches, compact enough for a duck blind.
• Weight is 7 pounds, a figure that soaks up recoil from heavy loads.
• The camouflage is Realtree Max-7 on the receiver, barrel and composite stock, which helps break up your outline.
• The chokes are Invector-Plus Flush in Full, Modified and Improved Cylinder, so you can match the load to the range.
• The front sight is fiber optic, which makes it fast to line up on a flushing bird.
• The recoil pad is Inflex 2, which reduces felt recoil on repeated shots.
