Description
The Mossberg SA-20 20 Ga, 22″ Barrel, 3″, Mossy Oak Obsession Synthetic is a gas-operated, semi-automatic shotgun designed for reliability in the field. It’s a lightweight, camo-clad workhorse built to handle 2¾” and 3″ 20-gauge shells, making it an ideal choice for upland game, turkey, and clays without the heavier 12-gauge recoil. I’ve put a few hundred target loads and a box of heavy 3″ through one, and it cycled everything without a hiccup—a solid testament to its simple, proven action.
Key Features
- Gas-Operated System: Softer recoil and reliable cycling with a wide range of 20-gauge loads.
- Mossy Oak Obsession Camo: Full synthetic stock and forend in a proven, effective pattern for concealment.
- 22″ Vent-Rib Barrel: A versatile length that’s quick-handling in thick cover but still gives you a good sight plane.
- 3″ Chamber: Handles everything from light target loads to potent 3″ magnums for turkey or waterfowl (with non-toxic shot).
- Lightweight Build: Comes in around 5.5 lbs, so you can carry it all day without fatigue.

Look, the beauty here is in its straightforward design. It’s a no-fuss tool that fits out of the box and gets the job done. The 22″ barrel gives it an overall length just over 42 inches, making it easy to maneuver in a blind or dense Missouri timber. At a hair over five and a half pounds, it’s a featherweight compared to many 12-gauges, which is a huge advantage when you’re covering ground for quail or pheasant. The price point of $486.16 is attractive for a reliable, name-brand autoloader with a full camo dip.
Who This Shotgun Is For
This is the go-to for the hunter who wants autoloader smoothness without the weight and punch of a 12-gauge. It’s perfect for new shooters, younger hunters, or anyone with a lighter frame who still needs dependable performance. Upland bird hunters, turkey hunters wanting a quick second shot, and recreational clay shooters will all find a friend in the SA-20. It’s also a fantastic, low-recoil option for home defense when loaded appropriately.
Pros & Cons
Pros: The gas system really tames recoil, making long practice sessions or hunts more pleasant. The full Mossy Oak Obsession coverage is durable and saves you money on aftermarket camo. It’s incredibly lightweight and points naturally. Reliability with mixed ammo is a strong point for a gun in this class.
Cons: As a value-focused model, it doesn’t have fancy furniture or adjustable stocks—it’s a basic, functional tool. The 4+1 capacity is standard but less than some competitors. Disassembly for cleaning is simple, but the gas system does require attention after heavy use.
Frequently Asked Questions
Q: Is the SA-20 reliable with light target loads?
A: Yes, that’s one of its strengths. The gas-operated action is designed to cycle both light 2¾” target loads and 3″ magnums reliably. I’ve had zero issues with standard 7/8 oz or 1 oz loads, which is crucial for practice and dove hunting.
Q: Can I use this for waterfowl hunting?
A: Absolutely, provided you use non-toxic shot (steel, bismuth, etc.) as required by law. The 3″ chamber gives you plenty of power for ducks over decoys. Just remember to check your state’s regulations on plug requirements to limit capacity to three shells.
Q: Are chokes included and what thread pattern does it use?
A: Yes, it typically comes with a set of interchangeable choke tubes (often Improved Cylinder, Modified, and Full). The SA-20 uses the common and versatile Mobilchoke thread pattern, which means you have a huge aftermarket selection from brands like Carlson’s and Truloke for specialized hunting or shooting sports.
Here’s the thing—the Mossberg SA-20 in Mossy Oak Obsession delivers proven performance without overcomplicating things or breaking the bank. It’s a trustworthy companion that ships to Missouri and compliant US states. If you’re looking for a lightweight, soft-shooting 20-gauge autoloader that’s ready for the season, this one deserves a close look.
