The CZ Swamp Magnum 12GA 3.5" 30" MOBL Camo shotgun is purpose-built for serious waterfowl hunters who demand a reliable over/under for long days in the blind. This 12-gauge brings real firepower to duck and goose hunting with its 3.5-inch magnum chambers, letting you reach out confidently for birds that other shooters would have to pass on. The Swamp Magnum stands out in CZ's lineup with an automatic safety that engages every time you open the action—a smart safety feature that keeps everyone in the boat protected when guns are being handled in close quarters.
Built for wet, punishing conditions, the Swamp Magnum wears a durable polymer stock finished in MOBL camouflage, paired with blackened metalwork that won't flash in the morning light. The 30-inch barrels are the sweet spot for most waterfowl hunting—short enough to swing quickly on passing birds, long enough to pattern modern waterfowl loads cleanly. At 7.1 pounds, it balances well without being a burden during long retrieves, and the 14.5-inch length of pull fits most hunters comfortably even when wearing heavy cold-weather gear.
The Swamp Magnum ships with five screw-in choke tubes, so you can dial in the right constriction for your load and distance. The single selectable trigger lets you choose which barrel fires first, giving you shot-selection flexibility on the water. A receiver-mounted optics rail is included if you want to add a red-dot or shotgun scope for improved target acquisition in low light. Automatic ejectors throw empties clear when you crack the action open, keeping you in rhythm during fast-paced flights.

The shotgun includes five screw-in choke tubes so you can match constriction to your load distance and hunting situation. The multi-choke system lets you adapt to everything from close-range timber shots to open-water pass shooting.
The automatic safety on the Swamp Magnum is a feature that engages every time you open the action, adding an extra layer of protection in the blind where multiple guns are being handled. If you prefer a manual safety, you may want to look at other CZ over/under models.
Yes. The shotgun includes a receiver-mounted optics rail, so you can install a shotgun scope, red-dot sight, or similar optic if you want to improve target acquisition, especially in low-light conditions common in early-morning waterfowl hunting.
The single selectable trigger lets you choose which barrel—top or bottom—fires when you press the trigger first. This gives you shot-selection flexibility, so you can decide which barrel's choke and load you want to use before taking your shot.
