Description
The Winchester SX4 Cantilever Buck 12 Gauge 22-inch is a purpose-built semi-auto slug gun that turns your shotgun into a precision deer-hunting tool. It comes from the factory ready for optics, with a fully rifled barrel and a cantilever rail so your scope stays zeroed to the barrel. This is the shotgun I hand to new slug shooters who want consistent accuracy without the learning curve of a traditional bead sight.

Key Features
- Fully Rifled 22-Inch Barrel — WHY IT MATTERS: Rifling spins the sabot slug for stable flight, delivering consistent sub-2-inch groups at 100 yards with quality ammunition.
- Weaver-Style Cantilever Rail — WHY IT MATTERS: The rail mounts directly to the barrel, not the receiver, so your scope stays zeroed every time you take the gun down for cleaning or transport.
- TruGlo Fiber-Optic Front Sight & Adjustable Rear Sight — WHY IT MATTERS: Even without a scope, you get a bright, fast sight picture in low light. The rear sight adjusts for windage and elevation right out of the box.
- Active Valve Gas System — WHY IT MATTERS: It cycles everything from light target loads to heavy 3-inch magnum slugs without manual adjustment, making it a great choice for youth shooters and new hunters.
- Inflex Technology Recoil Pad — WHY IT MATTERS: The pad directs recoil down and away from your shoulder, reducing felt recoil by up to 54% compared to standard pads. Your kids will thank you at the range.
Who It’s For
This shotgun is built for the family hunter who wants one gun that does it all: deer season with slugs, turkey with a scope, and even casual target shooting. It’s especially good for new shooters because the gas system tames recoil and the cantilever rail removes the hassle of re-zeroing. If you’re teaching a teenager to hunt slugs, this is the platform I recommend.
Pros / Cons
- Pros: Reliable cycling with a wide range of loads, excellent recoil reduction, factory-ready for optics, drop-out trigger group makes cleaning simple.
- Cons: The synthetic stock has a slightly hollow feel in very cold weather, and the included rear sight is plastic—functional but not as durable as metal.

Frequently Asked Questions
What type of ammunition does the Winchester SX4 Cantilever Buck cycle reliably?
According to Winchester specs, the Active Valve system cycles 2¾-inch target loads, 3-inch magnum slugs, and everything in between. I’ve personally run 1-ounce Foster slugs and 2¾-inch light field loads without a single hiccup.
Can I mount any scope on the cantilever rail?
Yes, the rail is a standard Weaver-style base. You can mount any scope with Weaver or Picatinny rings. For slug hunting, I recommend a 1-4x variable scope for close timber and longer field shots.
Is this shotgun suitable for a youth or small-framed shooter?
Yes, the 22-inch barrel keeps the overall length manageable, and the Inflex recoil pad makes a big difference. I’ve taught 14-year-olds to shoot this gun comfortably with 2¾-inch sabot loads.
How do I clean the drop-out trigger group?
Push out the two retaining pins, and the entire trigger group lifts out. No tools needed. Wipe it down with a dry cloth, apply a light coat of CLP, and reassemble. It takes less than a minute.
