About this product
The Mossberg SA-20 Turkey 20 Gauge Mossy Oak Greenleaf is a purpose-built semi-automatic shotgun designed specifically for turkey hunting with optimized patterning and fast target acquisition. It combines sub-gauge handling with weather-resistant durability and optics-ready features. This firearm represents Mossberg's commitment to specialized hunting platforms that balance performance with practical field considerations.
What is the Mossberg SA-20 Turkey used for?
The SA-20 Turkey is designed exclusively for turkey hunting, providing tight patterns at extended ranges with its specialized choke and sight system. The Extended Turkey choke tube delivers consistent #4 through #6 shot patterns at 40+ yards, while the fiber-optic/ghost-ring sight combination enables rapid target acquisition in low-light conditions. This shotgun handles 2¾" and 3" 20-gauge shells specifically engineered for turkey loads.
How does the Mossberg SA-20 Turkey compare to the Stevens 555 Sporting O/U 20 Gauge?
The SA-20 Turkey outperforms the Stevens 555 Sporting O/U 20 Gauge for rapid follow-up shots and extended pattern consistency, though it sacrifices the over-under's reliability in extreme conditions. While the Stevens 555 offers dual-barrel versatility and simpler mechanical operation, the Mossberg's semi-automatic action provides faster second and third shots—critical when dealing with multiple birds or missed opportunities. The Mossberg's drilled and tapped receiver also allows for optic mounting, unlike the Stevens' fixed rib configuration.
What does it weigh and what are the dimensions?
The SA-20 Turkey weighs 6.2 pounds empty and measures 46.5 inches overall with its 24-inch vent-rib barrel. The 12.75-inch length of pull accommodates most adult shooters while maintaining maneuverability in blind setups, and the synthetic stock contributes to the lightweight handling characteristics that make this shotgun suitable for extended carries through rough terrain.
Who is this NOT for?
This shotgun is not suitable for waterfowl hunters or those requiring 3½" chamber compatibility for maximum payloads. The Mossy Oak Greenleaf finish provides limited concealment in snow or desert environments, and the semi-automatic action may be less reliable than pump actions in extreme mud or sand conditions. Waterfowl hunters should consider the Stevens 555 Sporting 20 Gauge with its more versatile choke options.
What's in the box?
The package includes the shotgun with installed Extended Turkey choke, one additional modified choke tube, and a 3-piece choke wrench set. Mossberg provides a basic owner's manual and warranty documentation, but notably excludes any cleaning equipment or additional choke tubes beyond the turkey-specific configuration—expect to purchase additional tubes separately for other hunting applications.
Is the Mossberg SA-20 Turkey worth it at $802.99?
At $802.99, the SA-20 Turkey delivers exceptional value for dedicated turkey hunters who require semi-automatic reliability and specialized patterning. The optics-ready receiver and premium sight package would cost $200+ to add to a basic shotgun, while the Mossy Oak Greenleaf finish provides $150+ value over basic synthetic finishes. For hunters who specifically target turkeys 15+ days per season, this shotgun justifies its premium through dedicated performance features.

Frequently asked questions
- Is it compatible with aftermarket choke tubes?
- Yes, the SA-20 Turkey uses Mossberg's Accu-Choke thread pattern, compatible with all standard Accu-Choke tubes. The included wrench accommodates most aftermarket options, though some precision turkey chokes may require specific tools. Pattern testing is recommended with any non-factory tube.
- Does it fit youth or smaller-framed shooters?
- The 12.75-inch length of pull may be excessive for shooters under 5'6" or youth hunters. Mossberg doesn't offer a compact stock option for this model—consider the <a href="/products/stevens-555-sprtng-ovr-undr-20ga-cmp/">Stevens 555 Sporting Compact 20ga</a> with its 13-inch LOP for smaller frames.
- How long does shipping take to FFL dealers?
- Standard shipping to licensed FFL dealers takes 3-5 business days after order processing. All firearms require shipment to your chosen FFL holder—we recommend contacting your dealer beforehand to ensure they accept shipments from online retailers.
- Can I return it if it doesn't pattern well?
- Firearms sales are final once transferred through an FFL, though warranty defects are covered by Mossberg's limited lifetime warranty. Pattern testing should be conducted before any modifications—we recommend testing with Federal Premium Turkey Loads 20ga #5 shot at 30 yards to establish baseline performance.
