SX4 Built 4 Speed
Built 4 Ergonomics
Improved Ergonomics

Slim, light, better swing

One of the first things experienced shooters notice about the new Super X®4 is the gun’s IMPROVED ERGONOMICS. It’s LIGHTER OVERALL and THE PISTOL GRIP IS SLIMMER AND MORE ERGONOMIC, regardless of which hand you use to pull the trigger. The gun’s overall balance point has been moved slightly forward to CREATE A MORE FLUID SWING, BETTER TARGET TRACKING AND SMOOTHER FOLLOW-THROUGH.

Length of Pull Spacers

Adjusts to fit you.

The fit and balance of a shotgun stock are critical factors of how well you’re able to shoot it. The new Super X®4 comes with polymer LENGTH OF PULL SPACERS that fit between the stock and the recoil pad. When adjusted properly you shoulder the shotgun with a smooth confidence and “felt recoil” is greatly diminished. Synthetic stock Super X4 models come with one spacer already installed to provide a standard 14 1/4" length of pull, and include one additional spacer in the box. Wood stock models include two length of pull spacers in the box. When you remove or add a spacer, you change the length of pull by 1/4". Additional spacers are available from your Winchester Repeating Arms dealer, allowing you to custom fit the Super X4 to your exact length of pull.

Easy Controls

Glove friendly controls

The new Super X®4 features a LARGER BOLT HANDLE and an OVERSIZED BOLT RELEASE BUTTON for easier engagement and faster operation; two very important features when your hands are cold and wet or when you’re wearing gloves. The shell carrier and bolt release button are coated with Nickel Teflon® to reduce friction and help prevent corrosion.

Reversible Safety

Generously sized, reversible safety

The new Super X®4 features a LARGER BOLT HANDLE and an OVERSIZED BOLT RELEASE BUTTON for easier engagement and faster operation; two very important features when your hands are cold and wet or when you’re wearing gloves. The shell carrier and bolt release button are coated with Nickel Teflon® to reduce friction and help prevent corrosion.

Length of Pull Spacers

Reduce felt recoil

The newest evolution of the INFLEX TECHNOLOGY RECOIL PAD ON THE SUPER X®4 FURTHER REDUCES “FELT RECOIL.” Specially shaped rib structures located inside the pad help direct and channel the recoil impulse, moving the comb down and away from your cheek to reduce “felt recoil” to very manageable levels, even when shooting heavy magnum loads. The new pad’s LARGER FOOTPRINT SPREADS RECOIL FORCES OVER A WIDER AREA for further cushioning.

Built 4 Adaptability

Like the original Super X®3, the Super X®4 uses the proven ACTIVE VALVE GAS SYSTEM that automatically self-adjusts to allocate the exact gas pressure necessary to reliably cycle a wide range of loads commonly used for hunting or target shooting. When firing the heaviest magnum loads in 3 1/2" models, gases vent upward and a portion of them are vented forward out the Quadra-Vent ports in the forearm to help regulate bolt speed. Both 3" and 3 1/2" Super X4 shotguns will reliably cycle even 1 1/8 oz., 2 3/4" light loads. Excess gases from heavy loads are channeled through the forward QUADRA-VENT™ ports for cleaner and more reliable operation.

LOAD DIVERSITY means a Super X®4 can reliably shoot them all, from light factory field shells to heavy magnum waterfowl and turkey loads. That’s why the proven Active Valve on the Super X4 makes it the most versatile autoloader on the range, in the marsh and in the field.

Back-Bored Technology

Back-Bored Barrel Technology

One of the first things experienced shooters notice about the new Super X®4 is the gun’s IMPROVED ERGONOMICS. It’s LIGHTER OVERALL and THE PISTOL GRIP IS SLIMMER AND MORE ERGONOMIC, regardless of which hand you use to pull the trigger. The gun’s overall balance point has been moved slightly forward to CREATE A MORE FLUID SWING, BETTER TARGET TRACKING AND SMOOTHER FOLLOW-THROUGH.

Drop-Out Trigger Group

Self Aligning Removable Trigger Group

The Super X®4 has a DROPOUT TRIGGER GROUP that’s easy to remove for detailed cleaning or lubrication. The SELF ALIGNING BOLT CARRIER LINK makes it easier than ever to reassemble.

Chamber

Chrome Plating

CHROME-PLATED CHAMBER AND BORE are critical for today’s steel or Hi-Density (HD) shot. Hard chrome makes the surfaces highly resistant to wear and gives you superior protection from rust and corrosion. That’s why all smoothbore Super X®4 shotguns feature a hard-chromed chamber and bore.

Invector-Plus Choke Tubes

Invector-Plus Choke Tubes

From the duck blind to the firing line, the INVECTOR-PLUS CHOKE TUBE SYSTEM is the world’s most consistent. Because the threads are located at the bottom of the choke tube they seal out corrosive gases better. The tube’s thicker walls make Invector-Plus chokes much stronger than any other choke tube system, yet they remain easy to remove and clean. They are more concentric with the bore and thus produce more even, consistent shot patterns. The Super X®4 comes with full, modified and improved cylinder flush-mounted choke tubes so your gun is ready for anything, right out of the box. Additional choke tubes are available at your local Winchester Repeating Arms dealer.
