The Mossberg SA-20 is a 20-gauge semi-automatic shotgun built for hunters and clay shooters who value nimble handling and manageable recoil. With its gas-operated system and lightweight profile, this autoloader swings fast through thick cover and reduces fatigue over a full day in the field—making it an excellent choice for upland hunting, woodland game, or casual sporting clays work. The 22-inch barrel and fixed 14.25-inch length of pull keep the gun compact and intuitive, whether you're navigating brush or shouldering quickly at fast-moving targets.
The SA-20 comes ready to work with a vented rib for consistent sight picture, a Picatinny rail on top for optics or accessories, and a fiber-optic ghost ring sight setup for both speed and precision. The synthetic Mossy Oak Greenleaf furniture blends into hunting terrain while standing up to hard use, and the 4+1 round capacity (plus the included extended turkey choke tube) gives you flexibility for different game and conditions. At 5.5 pounds, this gas gun cycles smoothly without punishing your shoulder, a real advantage when you're putting in a full morning of shooting.
Mossberg's reputation for reliability and field durability backs this one, and the 20-gauge platform itself is a sweet spot for hunters who want less recoil and noise than a 12 without sacrificing practical effectiveness. If you're new to shotgun hunting or looking for a lighter, faster-handling autoloader to complement a heavier gun in your rack, the SA-20 proves that smaller gauge doesn't mean short on capability.

Yes. The 22-inch barrel, lightweight design, and quick-handling profile make it well-suited to both upland game in brush and clay target sports. The gas-operated system keeps recoil mild, so you can shoot all day comfortably, and the vented rib and ghost ring sights help you stay on target.
The shotgun comes with an extended turkey choke tube already installed. It accepts standard choke tubes, so you can swap in different chokes for different hunting situations or clay targets.
Yes. The SA-20 features a top Picatinny rail, so you can mount a red-dot, reflex sight, or low-power scope if you want an alternative to the fiber-optic ghost ring sights that come standard.
