The Mossberg 835 Ulti-Mag Waterfowl shotgun is engineered for shooters requiring broad ammunition versatility and consistent performance across diverse environments. This platform facilitates seamless transitions between 2.75-inch, 3-inch, and 3.5-inch 12 gauge shells, mitigating the need for multiple specialized shotguns. Its robust design ensures reliable feeding and ejection, critical for dynamic shooting scenarios and demanding field use.
Key Features
Multi-Load System
The 835 Ulti-Mag’s core design allows it to reliably cycle all standard 12 gauge ammunition, from light field loads to high-capacity 3.5-inch magnum shells. This versatility streamlines ammunition selection, adapting the shotgun’s performance to specific game or competition requirements without compromise.
Barrel Engineering
This model features a 28-inch vent rib barrel, precision-ported to mitigate muzzle rise and enhance shot stability. The overbored barrel design optimizes pattern density and reduces felt recoil. An included Accu-Mag choke set (Modified, Full, Improved Cylinder) provides the necessary flexibility to tune shot patterns for varied ranges and target presentations.
Reliability and Durability
Constructed for consistent operation under adverse conditions, the 835 Ulti-Mag incorporates dual extractors to ensure positive shell extraction. The durable synthetic stock and forearm are finished in Mossy Oak Shadow Grass Blades camouflage, providing a non-reflective, weather-resistant surface crucial for field concealment and long-term service life.
Target Acquisition
Equipped with a highly visible fiber optic front sight, this shotgun facilitates rapid target acquisition and precise aiming, even in challenging light conditions. The vent rib provides a clear sight plane, aiding in consistent lead estimation.
