Key Features
- Overbored 20-inch barrel – The .775-inch overbore diameter reduces felt recoil and produces denser, more uniform patterns with heavy turkey loads. That means more shot on target at 40 yards.
- Holosun HS407K micro red dot (installed) – This low-profile optic gives you a crisp 6 MOA dot for fast, both-eyes-open shooting. It’s shake-awake powered and fits flush on the receiver without adding bulk.
- Optic-ready receiver – The receiver is pre-drilled and tapped for micro red dots, so you can swap optics easily. No gunsmith needed.
- Mossy Oak Greenleaf camo stock – The synthetic stock resists moisture and scratches, and the camo pattern blends into spring turkey woods. The tang safety is easy to reach for right-handed shooters.
- 3.5-inch chamber – Accepts 2.75, 3, and 3.5-inch shells. You get full versatility for everything from dove loads to magnum turkey loads.
Who It’s For
This shotgun is built for turkey hunters who want a dedicated bird gun with a red dot already mounted. It’s also a great choice for youth shooters moving up to a full-size 12 gauge, because the overbored barrel softens recoil noticeably. If you hunt spring turkey or do pattern shooting at the range, this package saves you the hassle of buying and mounting a separate optic.
Pros and Cons
- Pro: Ready to hunt out of the box with a quality Holosun red dot.
- Pro: Overbored barrel delivers consistent, tight patterns.
- Pro: Durable synthetic stock with effective camo.
- Con: The 20-inch barrel limits reach for waterfowl or long-range slug use. It’s optimized for turkey hunting inside 40 yards.
Comparison: Mossberg 835 Ulti-Mag vs. Benelli Super Black Eagle 3 vs. Remington 870 Turkey

|---|---|---|---|
| Action | Pump | Semi-auto | Pump |

The Benelli Super Black Eagle 3 is lighter and semi-auto, but costs more than double the Mossberg. The Remington 870 Turkey is cheaper but lacks a red dot and has a 3-inch chamber. The Mossberg 835 Ulti-Mag offers the best value for hunters who want a pump action with a factory-installed optic and 3.5-inch capability.
