Winchester SX4 Upland Field Features The Winchester SX4 Upland Field runs on a self-adjusting Active Valve gas system that automatically meters gas based on the load being fired so light target loads and heavy waterfowl loads both cycle reliably without any manual adjustment. Back-Bored Technology opens the bore beyond standard dimensions which shortens the shot string and tightens patterns for cleaner more consistent hits on flushing birds. A Black Nitride surface treatment hardens the chamber and bore while resisting corrosion and a Nickel Teflon coating on the bolt and bolt carrier reduces friction and fights fouling which means fewer malfunctions across a long hunting season. The reversible crossbolt safety oversize bolt release button and larger bolt handle make the controls fast to find and operate under pressure whether the gun is being run by a right or left handed shooter. The gloss finish AAAA maple stock and forearm bring a traditional feel with modern checkering for a secure grip in wet or cold field conditions and the matte nickel plated receiver keeps glare off the gun during early morning and late evening hunts. An engraved upland game scene on the receiver gives the SX4 Upland Field a dressed-up look that still holds up to real use in the field. The 20 gauge chambering keeps the overall weight down for faster handling on quick-rising pheasants and quail while the 3 chamber still allows heavier loads for passing waterfowl. Three Invector-Plus choke tubes in full modified and improved cylinder a TruGlo fiber-optic front sight on the ventilated rib and an Inflex Technology recoil pad for reduced felt recoil round out a shotgun ready for sale at GrabAGun to upland hunters and wingshooters alike.
