Item # 1739 Style WNC-511205292 UPC 048702006876 Condition New Manufacturer [Winchester](https://www.kygunco.com/brand/winchester) Model SX4 Hand Right Hand Finish Black Round Capacity 4 Caliber 12 Gauge Action Semi-Auto Barrel Length 28 in Black synthetic stock and forearm, Inflex recoil pad, Truglo front sight, Active Valve system, Invector-Plus chokes and more. **The next level of performance.** This Super X4 follows on the heels of the most successful Winchester autoloader ever: the Super X3 Black Shadow. There would be no point to the new SX4 if it did not take function, handling and ergonomics to the next level. And it does. This is a dedicated hunting machine with it's all-black exterior that is definitely non-glare to prevent spooking game. Critical functional controls are larger and easier to operate -- a real benefit in damp weather and cold conditions. **The feel is right.** You will need to go to your dealer to prove this to yourself, but the grip area has been totally redesigned for improved comfort and pointability. It feels thinner and it feels right. The same goes for the forearm. Both have gripping panels positioned to help prevent slipping and the texture feels good against your hands especially when you are not wearing gloves. **Function sets it apart.** The list of features designed to improve your shooting is impressive. - SYNTHETIC STOCK WITH IMPROVED ERGONOMICS, A SMALLER PISTOL GRIP AND TEXTURED GRIPPING SURFACES give your hands a sure, non-slip grip. The non-glare matte black finish won't spook wary game - BACK-BORED TECHNOLOGY provides optimum shot patterns that are dense and even - INVECTOR-PLUS CHOKE TUBE SYSTEM offers consistent patterns to match your target situation - HARD CHROME-PLATED CHAMBER AND BORE make these surfaces highly resistant to wear and corrosion - TRUGLO® LONG BEAD™ FIBER-OPTIC FRONT SIGHT offers a true, precise sight picture - VENT RIB gives you a smooth, clean sighting plane **Mechanical Features** - SELF-ADJUSTING ACTIVE VALVE SYSTEM cycles a wide variety of loads while reducing “felt recoil” - QUADRA-VENT™ PORTS vent excess gases for cleaner operation - DROP-OUT TRIGGER GROUP allows for easy cleaning - AMBIDEXTROUS CROSSBOLT SAFETY is easily reversible - LARGER BOLT HANDLE AND BOLT RELEASE BUTTON are faster and easier to operate - LENGTH OF PULL SPACERS allow stock adjustments to achieve a perfect fit - INFLEX TECHNOLOGY RECOIL PAD directs “felt recoil” down and away from your cheek to reduce flinch and fatigue **SPECIFICATIONS** - Item Number 511205292 - UPC 048702006876 - Gauge 12 - Chamber Length 3.5" - Barrel Length 28" - Overall Length 49" - Length of Pull 14 1/4" - Drop at Comb 1 3/4" - Drop at Heel 2" - Weight 7 lbs 2 oz - Magazine Capacity 4, 2 3/4" shells - Rib Width 1/4" - Barrel Finish Matte - Stock Finish Matte - Chokes Included Full, Modified, Improved Cylinder - Receiver Finish Matte Black - Dura Touch Finish No - Chamber Finish Chrome Plated Chamber and Bore - Front Sight Fiber Optic - Choke System Invector-Plus Flush - Barrel Material Steel - Stock Material Composite - Recoil Pad Inflex 1, Small with Hard Heel Insert - Checkering Textured Grip Panels - Sling Swivel Studs Matte Blued - Receiver Material Aluminum Alloy - Trigger Finish Matte Black - Trigger Guard Finish Matte Black - Bolt Slide Finish Matte Blued - Magazine Type Tubular - Trigger Material Alloy - Trigger Guard Material Alloy - Trigger Guard Engraving None - Choke Wrench Included Flat Wrench ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
