Core specifications that matter in the blind

At a glance, the MOSSBERG 835 ULTI-MAG WATERFOWL packs a set of sensible specs for migratory bird seasons: Action: Pump; Gauge: 12; Chamber: 3.5″; Capacity: 6; Barrel length: 28″ vent rib ported; Overall length: 48.75″; Weight: 7.75 lb; Length of pull: 14.5″; Stock: Synthetic; Sights: Fiber optic; Chokes: Accu-Mag set; Finish: Mossy Oak Shadow Grass Blades. Priced at $519.99, it positions itself as a workhorse option with features that typically appear on higher-end field guns.

Why these specs matter

The 12-gauge chambered for 3.5″ shells gives you the flexibility to run heavy-magnum waterfowl loads when you need long-range patterning or dense payloads for larger species. A 28″ vent rib barrel aids in sighting and follow-through, while porting reduces muzzle climb to help you get back on target for follow-up shots. The 6-round magazine is generous for field work, and the synthetic stock paired with a ventilated recoil pad keeps the system ready for wet conditions and extended carries.

Field features and handling

In cold, wet marshes you need a shotgun that functions without fuss. The pump action on the Ulti-Mag is designed to be positive under adverse conditions; there are fewer moving parts to foul or freeze compared to semiautomatic systems. The fiber optic sight adds a bright aiming reference for low-light shoots common at dawn and dusk. The Accu-Mag choke set gives you patterning options out of the box—tighten up for longer shots or open the spread for closer, tighter flocks.

Recoil and ergonomics

At 7.75 pounds with a 28″ barrel, the weight of the 835 balances recoil and carry comfort. The ventilated recoil pad helps cushion follow-through, which matters when you’re running heavy steel or magnum loads. The 14.5″ length of pull is a standard fit for most hunters; if you need adjustments, aftermarket spacers or a custom pad can tailor the fit without sacrificing the reliable function of the pump group.

Durability and finish

The Mossy Oak Shadow Grass Blades finish is applied to rugged synthetic furniture and helps the gun blend in on marsh edges. Synthetic stocks resist swelling and finish degradation from exposure to moisture, salt, and mud. The ported vent rib barrel is built to shed water and help maintain sight picture—two practical advantages when retrieving birds or shooting from a blind where water and weather are constant factors.

Chokes, ammo, and patterning

The Accu-Mag choke set included with the MOSSBERG 835 ULTI-MAG WATERFOWL gives hunters a quick way to tune patterns for different distances and load types. With 3.5″ capability, pattern testing with both waterfowl steel and lead replacements is essential. We recommend running pattern tests at realistic distances for your hunting area; the vent rib helps maintain a consistent sight plane while you evaluate pellet spread and point of impact.

Practical uses and who this fits

This shotgun is tailored for loaders and blinds where reliability and simplicity trump rapid-fire automation. Waterfowlers who frequently run mixed loads or rely on heavy magnum shells will appreciate the 3.5″ chamber and beefy magazine capacity. Youth or smaller-framed hunters may want to test the length of pull and consider sling or pad modifications. Guides and outfitters who need a durable, serviceable shotgun for a variety of clients will find the synthetic stock and proven pump mechanism advantageous.

Maintenance tips from the blind

Simple care keeps the 835 running: keep the action and magazine tube clean of grit, lightly oil the sliding surfaces, and inspect the vent rib and barrel for obstructions before each outing. The synthetic stock tolerates field cleaning—wipe down with a damp cloth and dry thoroughly. Regular choke maintenance and proper torque on the choke tubes maintain optimal patterning over the seasons.
