Winchester SX4 Upland Field Features The Winchester SX4 Upland Field runs on Winchester s Active Valve gas system which self-adjusts to cycle both light target loads and heavy hunting shells reliably. Back-Bored Technology widens the barrel s internal diameter to reduce felt recoil and tighten shot patterns compared to standard bore barrels. 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 rust buildup. The drop-out trigger group simplifies cleaning by allowing the entire fire control assembly to be removed as a single unit. The gloss blued 26 inch vent rib barrel pairs with a matte nickel-plated receiver featuring upland game scene engraving giving the SX4 Upland Field a distinctive traditional appearance in the field. The grade AAAA maple stock carries a gloss finish and traditional checkering while the larger bolt handle and oversize bolt release button make the action easier to manipulate with cold or gloved hands. A TruGlo fiber optic sight on the ventilated rib barrel speeds up target acquisition on crossing birds. Finished with an Inflex Technology recoil pad and three Invector-Plus choke tubes in full modified and improved cylinder the SX4 Upland Field is a complete upland package available for sale at GrabAGun.
