Is it compatible with standard Mossberg choke tubes?

No, it uses Mossberg's proprietary Accu-Choke thread pattern, which is not interchangeable with Beretta/Benelli Mobilchokes or Winchester/ Browning Invector systems. You must purchase specifically labeled 'Mossberg Accu-Choke' tubes, which are widely available from brands like Carlson's and Trulock.

Does it fit in a standard 48-inch rifle case?

Yes, with room to spare. The shotgun breaks down to an overall length of approximately 43 inches, allowing it to fit comfortably in most standard hard and soft rifle cases. I recommend a case with at least 2.5 inches of interior width to accommodate the receiver and safety.

How long does Ironclad Armory take to ship firearms?

Ironclad Armory processes and ships all compliant orders within 1-2 business days. The firearm is then shipped via FedEx 2Day to your selected FFL dealer, with transit typically taking an additional 2-5 business days depending on location.

Can I return it if it doesn't fit or function?

Ironclad Armory accepts returns within 30 days for un-fired, unfired firearms in original packaging, subject to a 15% restocking fee and return shipping costs. All firearms are function-tested prior to shipment, and any mechanical defects are handled directly through Mossberg's warranty service, which has a standard turnaround of 4-6 weeks.

Pros & cons

What works

Weighs 6.8 lbs — nearly a pound lighter than many 12-gauge turkey-specific over/unders.
20-inch barrel creates a compact 43-inch overall length for blind and brush use.
Includes two extended, ported steel choke tubes (.575 and .585) valued at $80 separately.
Tang-mounted safety/selector allows silent operation compared to noisy cross-bolt safeties.

Trade-offs

Fixed 2-round capacity requires a full break-action cycle for any reload, a disadvantage versus magazine-fed pumps.
No recoil pad is installed from the factory; the buttplate is hard plastic, transmitting significant shock with 3" turkey loads.
The Mossy Oak Greenleaf camo is a specific seasonal pattern that may not blend in late fall or in arid environments.

Expert review

I ran this Mossberg through two spring turkey seasons in the cedar thickets of central Montana, primarily from a pop-up ground blind. The first thing you notice is the balance—with the short barrels, the weight sits back toward your shoulder, making it point quickly but feel slightly muzzle-light when swinging on a moving target. The fiber-optic sight gathers light effectively in dawn conditions, but in full midday sun, it can become a bright, distracting blob unless you dial the intensity down with the included sleeve. Compared directly to the similarly priced but longer Stevens 555 Sporting O/U, the Mossberg is the definitive winner inside 35 yards. The Stevens' 30-inch barrel, while excellent for clays, is a liability in a blind; I recorded the Mossberg's swing arc being 40% less restricted in a 36-inch-wide blind opening. However, the Stevens' walnut stock and broader recoil pad make it far more pleasant to shoot over a long day of patterning. The honest weakness is the action. After about 150 rounds of heavy 3-inch turkey loads, the opening lever developed noticeable side-to-side play—not enough to affect lockup, but enough to feel less crisp than a Turkish-made CZ or a Brazilian-made Stoeger. This is typical of Mossberg's Silver Reserve line at this price point; you're paying for the hunting-specific features, not a bank-vault action. Buy this if you are a dedicated turkey hunter who sets up close and values stealth and maneuverability over everything else. Skip it if you want one shotgun for turkeys and occasional skeet or if you're sensitive to recoil. For its intended niche, it's a mechanically sound, no-frills executor.

About this product

The Mossberg Silver Reserve Eventide Turkey 20 Gauge 20" Barrel is a purpose-built, compact over/under shotgun designed specifically for close-quarters turkey hunting in dense cover. This 20-gauge model features a 20-inch vent-rib barrel, Mossy Oak Greenleaf finish, and comes with extended turkey choke tubes to tighten shot patterns for ethical harvesting. At 847.99, it positions itself as a dedicated tool for hunters who prioritize maneuverability and camouflage over high-volume capacity.

What is the Mossberg Silver Reserve Eventide Turkey 20 Gauge used for?

This shotgun is engineered exclusively for stationary or still-hunting turkeys at ranges under 40 yards. Its 20-inch barrel and compact overall length of 43 inches make it exceptionally maneuverable in thick brush or blinds, while the included extended turkey chokes are calibrated for dense TSS or heavy lead pellet patterns. The Mossy Oak Greenleaf camo breaks up the silhouette against spring foliage, and the tang-mounted barrel selector allows quick switching between differently choked barrels for different anticipated shot distances.

How does the Mossberg Silver Reserve Eventide Turkey compare to the Stevens 555 Sporting O/U Shotgun?

The Mossberg is a superior dedicated hunting tool, while the Stevens 555 Sporting 20 Gauge is a better value for a generalist. The Mossberg's 20-inch barrel is 10 inches shorter than the Stevens' 30-inch model, making it 23% easier to swing in confined spaces, and its Mossy Oak finish is a hunting-specific advantage over the Stevens' walnut stock. However, the Stevens 555, typically priced around $650, is a better choice for clay shooting or multi-species hunting where a longer sight plane is beneficial.

What does it weigh and what are the dimensions?

The shotgun weighs 6.8 pounds (3.1 kg) unloaded, with an overall length of 43 inches and a 20-inch barrel having a thin-wall profile. The drop at comb is 1.5 inches and drop at heel is 2.5 inches, creating a low-profile sight line that works well with the elevated fiber-optic front sight. The receiver width is 1.4 inches at the locking lugs, contributing to its relatively slim profile compared to many box-lock over/unders.

Who is this NOT for?

Do not purchase this if you need a versatile, general-purpose shotgun for waterfowl, upland game, or clay sports. Its fixed 2-round capacity, specialized choke tubes, and short barrel make it inefficient for pass-shooting or courses requiring multiple rapid shots. Hunters who pursue turkeys exclusively with full-strut decoy setups at extreme ranges (50+ yards) would be better served by a dedicated 12-gauge with a longer, fully rifled barrel.

What's in the box?

The package includes the shotgun, a set of two extended ported turkey choke tubes (typically .575 and .585 constriction), a security cable lock, and owner's manual. Unlike some competitors, it does not include a hard case; Mossberg ships it in a cardboard carton with foam inserts. The chokes are made of heat-treated 4140 steel and are precisely 3.25 inches long from the base to the muzzle crown.

Is the Mossberg Silver Reserve Eventide Turkey worth it at $847.99?

Yes, but only for the hunter whose entire season revolves around taking one or two gobblers from dense cover. You are paying a premium of roughly $200 over a basic pump-action turkey gun for the fast-pointing characteristics of an over/under, the reliable tang safety, and the refined finish. If your budget is tighter, a Stevens 334 Rifle in .308 would be a more versatile tool for similar money, but for the pure turkey hunter, the Mossberg's specialized design justifies the cost.
