CZ-USA Swamp Magnum 12 Gauge 3.5" Semi-Auto Shotgun 30" Barrel

The CZ-USA Swamp Magnum delivers maximum power for serious waterfowl hunters who demand reliability in harsh conditions. This 12-gauge semi-automatic shotgun chambers 3.5-inch magnum shells, providing the knockdown power needed for high-flying geese and challenging weather conditions.

What Makes This Different

The Swamp Magnum features CZ's proven gas-operated system that cycles reliably with both 2¾-inch and 3½-inch shells without adjustment. The 30-inch barrel optimizes velocity for long-range shots while the oversized bolt and carrier handle the stress of magnum loads. Unlike many competitors, this shotgun maintains consistent cycling even when heavily fouled from extended hunting sessions.

Key Features

• Gas-operated semi-automatic action cycles 2¾" to 3½" shells reliably
• 30-inch barrel with ventilated rib maximizes downrange performance
• Realtree Max-5 camouflage pattern provides superior concealment in wetlands
• Black anodized aluminum receiver resists corrosion in marine environments
• Synthetic stock and forend won't warp or crack in extreme weather
• Five interchangeable choke tubes optimize patterns for various loads
• 2+1 capacity with 3-inch chamber for fast follow-up shots

Field performance centers on the gun's ability to function in conditions that stop other semi-automatics. The oversized loading port accommodates gloved hands during cold weather hunts. Hunters report consistent cycling with everything from light target loads to heavy 3½-inch steel shot. The long barrel provides excellent swing characteristics for crossing shots while maintaining balance despite the extended length.
