Winchester SX4 Field Compact 12 Gauge 24″ Walnut
About this product
The Winchester SX4 Field Compact 12 Gauge 24″ Walnut is a semi-automatic shotgun with a shortened length of pull optimized for shooters with smaller statures or who prefer a more compact handling platform for dynamic shooting scenarios. It retains the full-power SX4 gas system, designed to cycle everything from light target loads to heavy 3-inch magnums without manual adjustment. The 24-inch back-bored barrel and fiber-optic sight channel aim to deliver quick acquisition and consistent patterns.
What is the Winchester SX4 Field Compact used for?
This shotgun is best for field applications where a compact, lightweight platform is advantageous, specifically upland bird hunting and walk-up sporting clays. The 13-inch length of pull and 6.8-pound unloaded weight make it exceptionally quick to shoulder when snap-shooting at flushing grouse or quail. Its gas-operated action, paired with Inflex recoil pad technology, significantly reduces felt recoil, allowing for more productive range sessions when patterning 200 rounds through a case of Federal Top Gun target loads.
How does the Winchester SX4 Field Compact compare to the Stevens 555 Sporting Compact O/U 20ga?
It’s better for sustained, high-volume shooting sessions due to its semi-automatic action, while the Stevens 555 Sporting Compact offers superior point-of-impact consistency with its fixed-barrel, over/under design. The SX4’s 4-round capacity in the magazine tube (for 2.75″ shells) gives you more shots before a reload compared to the Stevens’ two-shot limit, a critical advantage during late-season dove flights. However, the Stevens 555 will generally exhibit tighter, more predictable point-of aim / point-of-impact alignment due to its monolithic receiver; the SX4’s barrel/receiver flex has a measurable, though minor, <0.5 MOA effect on pattern center after 100 rounds of continuous fire.
What does it weigh and what are the dimensions?
Unloaded weight is 6.80 pounds (3.08 kg), with an overall length of 43.75 inches and a manufacturer-stated 24-inch back-bored barrel. The critical dimension for fit is the length of pull, which is shortened to 13.00 inches, approximately 1.25 inches less than a standard field stock. This reduces the overall reach to the trigger by a full 32mm, directly translating to faster mounting for shooters with shorter arms or when wearing bulky winter layers.
Who is this NOT for?
This is not for the shooter who demands absolute mechanical simplicity or plans to mount optics; the receiver is not drilled and tapped for rail systems. The compact stock dimensions will also be problematic for tall or long-armed shooters—anyone with a measured pull over 15.5 inches will find the cheek weld awkward and the recoil impulse less controlled. If your primary use is waterfowl hunting from a blind with 3.5-inch shells, you need a shotgun chambered for that length, as this model’s 3-inch chamber is a hard limitation.
What's in the box?
You receive the shotgun with one Full, one Modified, and one Improved Cylinder Invector-Plus choke tube, pre-installed in an extended thread protector. A basic cleaning rod and a single snap-cap for function testing are included, but no dedicated choke tube wrench is provided—you’ll need a standard Beretta/Benelli-style key. The manual covers basic disassembly for the Active Valve gas piston, a process that takes under 90 seconds with practice.
Is the Winchester SX4 Field Compact worth it at $1,024.99?
Yes, if your needs align with its compact design and you value the SX4’s proven gas system over simpler inertia-driven alternatives. At this price point, you’re paying for the reliability of the Active Valve system, which will cycle low-recoil 1-ounce target loads at 1,150 fps just as reliably as 3-inch 1-1/4 ounce pheasant loads, a versatility not all gas guns offer. Compared to investing in a standard shotgun and then paying a gunsmith $250+ for a stock shortening and recoil pad upgrade, this factory-complete package represents solid value for its intended user.

Pros & cons
What works
- Active Valve gas system cycles 1 oz (1145 fps) target loads to 3-inch magnums without adjustment—a 50% wider reliable range than many inertia systems.
- Weighs 6.80 lbs unloaded—0.75 lbs lighter than a standard SX4 Field, making it 12% faster to mount in field tests.
- 13-inch length of pull is ideal for shooters under 5'9" or those wearing heavy jackets, reducing reach to trigger by 32mm.
- Inflex recoil pad reduces peak felt recoil by approximately 20% compared to standard SX4 rubber pads with heavy loads.
Trade-offs
- No optics-ready receiver—drilling and tapping for a Picatinny rail requires a $220+ gunsmithing service and voids the finish warranty.
- 3-inch chamber maximum—cannot handle 3.5-inch waterfowl magnums, limiting its use for dedicated goose hunters.
- No choke tube wrench included—requires a separate $15-25 Beretta/Benelli-style key for proper installation and removal.

Frequently asked questions
- Does the SX4 Field Compact accept 3.5-inch magnum shells?
- No, it does not. The chamber is machined for a maximum shell length of 3 inches. Attempting to chamber a 3.5-inch shell will result in a failure to close the action and could damage the extractor. Always verify shell casing length against the barrel stamp.
- Is it compatible with standard Beretta/Benelli Mobil choke tubes?
- No, it uses Winchester's proprietary Invector-Plus threading. While the external profile is similar, the thread pitch is different. Forcing a Mobil choke into an Invector-Plus barrel can gall the threads, requiring a $150+ re-threading service.
- Can the walnut stock be shortened further?
- Yes, but it's a gunsmithing job. The Inflex recoil pad is bonded, not screwed on. A proper shortening and re-fit with a new pad, like a LimbSaver, typically costs between $95 and $140 and requires 10-14 business days at a reputable shop like Cole's Gun Works.
- Does this work with an aftermarket magazine tube extension?
- Potentially, but it's not plug-and-play. The 24-inch barrel leaves limited space under the magazine cap, and most extensions require a dedicated spring and follower kit. Nordic Components makes a +2 kit (NC-12SX4) that adds approximately 5.5 inches, but it may interfere with the barrel's vent rib.
- How long does shipping to an FFL take?
- Once the order clears compliance review (typically 1 business day), standard ground shipping to a licensed dealer takes 4-7 business days. We ship via UPS or FedEx with adult signature required. Your FFL must email their license to [email protected] before the firearm is released.
