Key Features
Defender Non-Glare (DFN) Finish
The SXP Marine Xtreme features the Defender Non-Glare (DFN) finish on the barrel and receiver. This proprietary coating provides superior protection against corrosion and abrasion, critical for operations in humid, saltwater, or other harsh conditions. The finish mitigates glare, maintaining a low profile.
Inertia-Assisted Pump Action
Equipped with Winchester’s signature inertia-assisted pump-action, the SXP Marine Xtreme ensures rapid and positive cycling. This mechanism utilizes recoil energy to facilitate smoother, faster operation, minimizing operator effort and enhancing follow-up shot capability.
Corrosion-Resistant Barrel
The 18-inch barrel is internally chrome-plated for exceptional resistance to bore corrosion and wear. This feature extends the barrel’s service life and simplifies cleaning, maintaining consistent performance over extended use cycles. The length optimizes maneuverability without significant velocity loss for defensive loads.
Ergonomic Synthetic Stock and Forend
The shotgun is fitted with a durable synthetic stock and a textured forend. The stock incorporates a pistol grip configuration for enhanced control and a secure purchase, particularly in wet or gloved conditions. The forend’s positive gripping surface ensures reliable pump operation under stress.
3-Inch Chamber
The 3-inch chamber accommodates a wide array of 12-gauge ammunition, from standard field loads to magnum defensive and specialized shells, offering operational versatility.
