Description
The Mossberg 500 Pump 20 Ga 22″ 3″ Mossy Oak Obsession Synthetic Stock Mossy is a purpose-built, camo-clad pump-action shotgun designed for the upland hunter or small-game shooter who needs a lightweight, reliable, and incredibly effective tool in the field. I’ve put hundreds of rounds through various 500 models, and this 20-gauge version in Mossy Oak Obsession is a standout for its handling and ready-to-hunt finish. It’s a classic pump gun that fits out of the box and ships to Missouri and compliant US states.
Key Features
- Mossy Oak Obsession Camo: Full coverage from the synthetic stock and forend right down the 22″ vent-rib barrel for superior concealment in spring and early-season environments.
- 20-Gauge Versatility: Chambered for 3″ shells, it delivers effective power for turkey, squirrel, and rabbit with significantly less recoil than a 12-gauge—a huge plus for younger shooters or those sensitive to kick.
- Proven Mossberg 500 Action: Dual action bars provide that famously smooth, reliable, and non-binding pump stroke. It’s a system I trust implicitly after years of hard use.
- Lightweight & Balanced: The synthetic furniture keeps the weight down, making it a joy to carry all day through thick cover. The balance point feels just right for quick mounting and swing.

Here’s the thing—at just over six pounds, this shotgun won’t wear you out. That 22″ barrel is the sweet spot for a hunting 20-gauge, offering a great sight plane and maneuverability without sacrificing too much velocity.

The price point of $432.95 makes it a serious value in today’s market for a camo-ready hunting tool.
Who This Shotgun Is For
This is the ideal first serious shotgun for a new hunter, especially a younger shooter stepping up from a .410. It’s also a perfect dedicated small-game and turkey gun for the seasoned hunter who wants a lighter, specialized rig. If you spend your autumns in the woods after squirrels or your springs in a blind, this Mossberg 500 configuration eliminates the need for aftermarket camo dipping. It’s ready on day one.
Pros & Cons
Pros: The Mossy Oak Obsession pattern is highly effective and factory-applied. The 20-gauge chambering offers manageable recoil. Mossberg’s pump action is arguably the most reliable in the world. The 22″ barrel is perfectly proportioned for hunting use. It’s a tremendous value for a complete, camo-finished package.
Cons: As a dedicated hunting model, it doesn’t include interchangeable choke tubes (it typically comes with a fixed Modified choke, which is great for all-around use). The synthetic stock, while tough, doesn’t have the classic feel of wood. Some may prefer a longer barrel for certain clay target games, but that’s not this gun’s primary role.
Frequently Asked Questions
Q: What choke does this model come with?
A: This specific Mossy Oak Obsersion model typically comes from the factory with a fixed Modified (Mod) choke tube installed. This is an excellent all-purpose constriction for hunting everything from upland birds to turkey with the right ammunition. It’s not designed to be swapped, keeping the profile clean and simple.
Q: Is the Mossberg 500 20-gauge suitable for home defense?
A: While any reliable firearm can serve in a defensive role, this 22″ barrel configuration is optimized for hunting and field carry. For home defense, a shorter 18.5″ barrel and cylinder bore choke are more standard. That said, with appropriate ammunition, it would be effective—it’s just not the ideal setup for tight quarters. Models like the Mossberg 500 Persuader or 590 are better suited for that role.
Q: Can I add a sling to this shotgun?
A: Absolutely. The synthetic stock and forend are pre-drilled and tapped for standard sling swivel studs. It’s a straightforward, no-gunsmithing-required upgrade. Popular sling brands like Butler Creek or Quake Claw make models that attach easily, making it even easier to carry on those long walks.
If you’re looking for a no-nonsense, hunt-ready 20-gauge that you can depend on season after season, this Mossberg 500 in Mossy Oak Obsession is available at firearms-missouri.com for Missouri residents and nationwide.
