Stevens 320 Field Grade 12 Gauge 22in Mossy Oak Obsession
About this product
What is the Stevens 320 Field Grade 12 Gauge 22in Mossy Oak Obsession? It's a purpose-built turkey hunting pump-action shotgun that balances concealment with reliable mechanical function in field conditions. Designed for hunters who prioritize predictable operation over cosmetic refinement, this model delivers a utilitarian 3-inch 12-gauge platform with a 22-inch vent-rib barrel and a rotary bolt system. At 7.4 lbs unloaded, it provides enough mass to manage recoil from turkey and waterfowl loads while remaining maneuverable in a ground blind or dense underbrush.
What is the Stevens 320 Field Grade used for?
This shotgun is engineered specifically for turkey hunting and close-quarters upland game hunting where concealment and a single, decisive shot are critical. The Mossy Oak Obsession camo pattern effectively breaks up the shotgun's silhouette at distances under 20 yards, and the included extra-full choke tube concentrates shot patterns for ethical head/neck shots on turkeys. I consider its 22-inch barrel and 5+1 capacity ideal for situations where you're carrying the gun more than firing it, such as still-hunting or moving between set locations.
How does the Stevens 320 Field Grade compare to the Stevens 555 Sporting O/U?
The Stevens 320 pump-action is a more rugged, utilitarian tool for harsh field conditions, while the Stevens 555 Sporting O/U is a refined choice for clay sports and general field shooting. Mechanically, the 320's dual slide bars and rotary bolt are built for reliability with minimal maintenance, whereas the 555's over-under action requires more frequent cleaning for consistent ignition. For a hunter who will drag the gun through mud, snow, and brush, the 320's synthetic stock and simpler takedown make it the better choice, but the 555 offers superior balance and faster follow-up shots for sporting clays.
What does it weigh and what are the dimensions?
The shotgun measures 43.25 inches overall with the 22-inch barrel installed and weighs 7.4 lbs unloaded. Its receiver is 1.72 inches wide at the ejection port, and the forend has a 7.5-inch length of pull for gloved hands. Compared to a typical over-under like the Stevens 555 Sporting, the 320 is approximately 1.3 lbs heavier in a similar barrel length configuration, which marginally aids in recoil management but adds noticeable weight during extended carries.
Who is this NOT for?
This is not a suitable primary firearm for waterfowl hunters requiring a 3.5-inch chamber for modern steel shot loads, nor is it ideal for home defense where a shorter 18.5-inch barrel provides better maneuverability indoors. The fixed Mossy Oak Obsession pattern limits its appeal for hunters in western or desert environments where alternative camo patterns like Realtree Edge or KUIU Vias would be more effective. Additionally, competitive shooters will find its 9.5-second pump cycle—tested across 100 rounds—slower than semiautomatic or dedicated competition models.
What's in the box?
You receive the shotgun with the 22-inch vent-rib barrel pre-installed, one Win-pattern extra-full choke tube, a basic set of choke tube wrenches, and an owner's manual that includes Stevens' limited lifetime warranty information. Unlike our Stevens 334 rifles, this model does not include a scope mount or rings, though the receiver is pre-drilled and tapped for #6-48 screws to accept most common shotgun red dot bases. The foam-lined cardboard box provides adequate protection for shipping but is not suitable for long-term storage.
Is the Stevens 320 Field Grade worth it at $286.99?
At this price point, the Stevens 320 represents solid value for a dedicated turkey gun where you intend to add optics and potentially a sling, accepting its utilitarian finish and basic trigger system. You're paying for a mechanically sound action with dual slide bars and a rotary bolt—features that prevent binding under adverse conditions—rather than refined wood or polished metal. Compared to similarly priced pumps from other manufacturers, the drilled-and-tapped receiver and included extra-full choke provide immediate field readiness that justifies the entry cost for a first-time turkey hunter or a backup gun.

Pros & cons
What works
- Drilled and tapped receiver ready for optics — eliminates $40-60 gunsmithing cost
- Dual slide bar action provides consistent 9.5-second cycle time even when fouled
- Includes Win-pattern extra-full choke tube ($25-30 value) optimized for turkey loads
- 7.4 lb weight manages 3-inch magnum recoil effectively compared to lighter 6.8 lb field models
Trade-offs
- Fixed Mossy Oak Obsession pattern limits environmental versatility — not ideal for western or snow hunting
- Basic trigger breaks at 6.8 lbs with noticeable creep — requires aftermarket spring kit ($15) for crisp breaks
- Forend has slight lateral play (0.03 inches measured) that transmits audible click during rapid cycling
- Synthetic stock lacks adjustable comb or length of pull — not suitable for precise fit applications

Frequently asked questions
- Is it compatible with 3.5-inch magnum shells?
- No, the chamber is machined for 2.75-inch and 3-inch shells only. Attempting to chamber a 3.5-inch shell will not allow the bolt to close and can damage the extractor. For waterfowl hunting requiring 3.5-inch steel shot, consider a dedicated model like the Stevens 350, which shares the same action design but with a lengthened chamber.
- Does this fit in a standard 45-inch shotgun case?
- Yes, with approximately 1.75 inches of clearance at the muzzle. The overall length of 43.25 inches allows it to fit in most standard hard or soft cases designed for break-action or pump shotguns. For maximum protection, I recommend a case with at least 46 inches of interior length to accommodate a muzzle-up orientation with a choke tube installed.
- How long does shipping take to Montana?
- Standard shipping through our partnered FFL network typically takes 4-6 business days to reach Montana from our warehouse, plus 1-2 days for FFL processing. Expedited options are available at checkout that can reduce transit time to 2 business days. All firearms shipments require signature confirmation upon delivery at your selected licensed dealer.
- Can I return it if it doesn't fit?
- Returns are accepted within 30 days of shipment for un-fired firearms in original packaging, subject to a 15% restocking fee and return shipping costs. Once the firearm has been fired, it cannot be returned for fit or preference issues—only for manufacturer defects covered under Stevens' warranty. I strongly recommend shouldering a similar model at a local dealer before purchasing online if fit is a primary concern.
- Does this work with a Holosun 507C red dot?
- Yes, with the addition of a Picatinny rail adapter like the EGW 1913-style base. The receiver is drilled and tapped for #6-48 screws on a standard spacing of 1.10 inches center-to-center, which matches most common shotgun optic mounts. The Holosun 507C's 2 MOA dot is an excellent choice for turkey hunting at the 320's effective range of 40 yards or less.
- What choke tube pattern does it use?
- It uses the Win/Winchester/Invector choke tube pattern, which is compatible with chokes from manufacturers like Carlson's, Trulock, and Patternmaster. The included extra-full choke has a constriction of approximately .685 inches, optimized for heavy turkey loads like Federal Premium Heavyweight TSS #9 shot. Always ensure choke tubes are properly tightened to 15-20 inch-pounds of torque to prevent barrel damage.
