Winchester SX4 Stealth combines the proven gas-operated SX4 platform with a distinctive hunting-green composite stock and forearm, a 71 cm barrel and a 12/76 chamber. This configuration is built around practicality, resistance to demanding outdoor conditions and predictable handling in a wide range of hunting situations.
The exact MoskovHunt version carries manufacturer code 511266361, with a 71 cm barrel, 4+1 capacity and the Invector Plus™ interchangeable choke system. Winchester's Active Valve gas system manages the operating gases automatically, while the Back-Bored barrel geometry is designed to support consistent shot-pattern performance.
Automatic management of the gas-operated action according to the cartridge being used.
SX4 uses a gas piston with Active Valve. The system regulates the operation of the gas action so the shotgun can function with a broad range of suitable loads within the specified gauge and chamber.
For a semi-automatic hunting shotgun, this is an important part of the platform: the action is designed to cycle reliably without requiring the user to manually tune the gas system whenever the load changes.
Winchester uses Back-Bored technology in the SX4 Stealth. The optimised internal barrel geometry is designed to make efficient use of the cartridge and reduce unnecessary pellet deformation as the shot charge travels through the barrel.
The exact MoskovHunt configuration uses a 71-centimetre barrel.
Internal barrel geometry developed to support efficient cartridge performance and consistent shot distribution.
The 71 cm version is specified with a 6 mm ventilated rib and fibre-optic front sight.
The barrel uses Winchester's proven Invector Plus™ choke system. This version is supplied with three interchangeable choke tubes, allowing different constrictions to be selected according to the intended use.
The tighter constriction among the supplied choke options.
A medium constriction and versatile option within the supplied set.
The more open constriction among the supplied Invector Plus™ tubes.
SX4 Stealth differs from the standard black composite variants through its characteristic hunting-green stock and forearm. Winchester specifies that the colour is integrated into the material rather than being only a superficial decorative finish.
Durable synthetic stock and forearm in the distinctive Stealth green colour.
Winchester uses an aluminium receiver on the SX4 Stealth platform.
The barrel uses a dark matte finish in keeping with the practical character of the model.
The rear of the stock uses Winchester's Inflex II recoil pad. It forms part of the SX4 design concept aimed at more comfortable handling with suitable loads.
Factory recoil pad developed to manage perceived recoil during use.
The exact 71 cm version is specified with a 362 mm length of pull.
A weight that keeps the shotgun stable without unnecessary bulk.
This SX4 Stealth is chambered in 12/76. The stated capacity is 4+1; all applicable legal restrictions and rules for the relevant hunting activity must always be observed.
One of the most widely used gauges for semi-automatic hunting shotguns.
