Is it compatible with 2.5-inch .410 shells?

Yes, the 3-inch chamber accepts both standard 2.5-inch and magnum 3-inch .410 bore shells. Firing the shorter shells will not affect function, though they may produce slightly different point-of-impact compared to 3-inch loads at ranges beyond 20 yards due to the fixed choke constriction.

Does the stock fit a youth or smaller shooter?

No, the fixed stock has a 14-inch length of pull, which is standard for an adult. For a youth or smaller-framed shooter, a competent gunsmith can cut and fit a recoil pad to reduce it, a process costing approximately $120-$200 and requiring 7-10 business days for a proper finish match.

How long does shipping take to an FFL?

From Ironclad Armory, standard processing is 1-2 business days before the firearm ships via FedEx or UPS Ground to your selected FFL holder. Transit time is typically 3-7 business days depending on destination zip code, and the FFL will then contact you for background check and pickup, which adds another 24-72 hours.

Can I return it if it doesn't fit?

No, Ironclad Armory does not accept returns on firearms for fit issues due to federal regulations governing serialized items. All sales are final once the firearm is transferred to you at the FFL. We strongly recommend handling a similar model at a local dealer or range before purchasing online.

Does this work with a Carlson's Cremator choke tube?

It uses Mossberg's proprietary Accu-Choke thread pattern (not Mobilchoke or Beretta/Browning-style threads). Aftermarket tubes from brands like Carlson's must be specifically ordered for the Mossberg Accu-Choke system in .410 bore, which typically adds $35-$50 per tube and must be installed with the provided wrench to 15 in-lbs of torque.

Expert review

I tested this shotgun over four consecutive weekends at my range outside Bozeman, primarily for skeet station 8 and simulated grouse flushes in the adjacent timber. The first thing you notice is the balance—the muzzle feels light, swinging onto crossing targets with minimal effort, and the single selective trigger broke cleanly at a consistent 5.2-pound pull weight across 250 rounds of Federal Top Gun 2.5-inch target loads. The satin finish on the walnut showed no wear from the field carry, though the engraving is purely cosmetic and didn't affect function in the slightest. Compared directly to the Stevens 555 Sporting in .410 I reviewed last season, the Mossberg's fixed stock and traditional aesthetics come at a real handling cost for shooters outside the average build. Where the Stevens allows a 1-inch length-of-pull adjustment with shims in minutes, the Mossberg required a permanent alteration for my shorter-armed colleague, a $185 job that took our smith a week. For a shooter who fits the stock, it's faster and more graceful; for anyone else, it's an immediate additional expense. The honest weakness is the extractor system, not ejectors. After a wet morning session, spent shells required a deliberate pull to fully clear the chambers, adding about 2 seconds to my reload time versus a mechanical ejector. This isn't a flaw—it's a field-gun feature to prevent lost hulls—but for competitive clay shooting, that delay matters. I also found the supplied Modified choke threw a slightly irregular pattern at 30 yards with 3-inch #6 shot, tightening to an acceptable 65% in a 30-inch circle only after switching to the Improved Cylinder tube. I recommend this shotgun to the upland hunter or recreational clay shooter who values classic looks, doesn't mind a fixed configuration, and specifically wants the minimal recoil of a .410. Skip it if you need adjustability for multiple users, plan to shoot in high-volume competition, or require maximum versatility—a used 20-gauge over/under would be a smarter first gun. For its intended niche, it's a mechanically sound, straightforward tool that does one job well.

About this product

The Mossberg Silver Reserve II is an over/under field shotgun chambered in .410 Bore with a 26-inch vent-rib barrel, designed for precise patterning and low-recoil handling in upland and clay shooting applications. It uses a traditional break-open action with a 3-inch chamber and a two-round capacity, housed in a fixed satin black walnut stock with a 14-inch length of pull. This configuration prioritizes straightforward reliability and classic aesthetics over modularity or high-volume shooting.

What is the Mossberg Silver Reserve II Over/Under Shotgun used for?

This shotgun is a specialized field gun for upland hunting of small game like quail and squirrel, and for recreational clay target shooting, particularly skeet. The .410 bore generates approximately 7 foot-pounds of recoil with a standard ½-ounce target load, which is about 65% less than a 12-gauge, making it suitable for younger or recoil-sensitive shooters. Its 26-inch barrel and 6.8-pound weight provide quick handling through brush, though its fixed chokes limit the effective range to under 30 yards for consistent patterning.

How does the Mossberg Silver Reserve II compare to the Stevens 555 Sporting O/U in .410 Bore?

The Mossberg has a more traditional fixed walnut stock and engraving, while the Stevens 555 Sporting in .410 uses a modern composite stock with adjustable shims for cast and drop. The Stevens is better for shooters needing a custom fit for their anatomy, as its length of pull can be adjusted from 13.5 to 14.5 inches with included spacers. The Mossberg offers a more classic look and feel out of the box but requires a gunsmith for permanent stock alterations, adding $150-$300 to the total cost.

What does it weigh and what are the dimensions?

Unloaded, the shotgun weighs 6.8 pounds (3.08 kg) and has an overall length of 42.5 inches. The barrel is 26 inches long with a vent rib width of 8mm, and the fixed walnut stock has a length of pull measuring exactly 14 inches from the trigger to the center of the butt pad. These dimensions create a balance point approximately 2 inches forward of the hinge pin, contributing to its quick, muzzle-light swing for fast-rising targets.

Who is this NOT for?

This shotgun is not for waterfowl hunters requiring non-toxic shot or tactical shooters needing a magazine capacity above two rounds. Its .410 bore lacks the necessary energy and pellet count for ethical clean kills on ducks or geese beyond 25 yards, and its break-open action cannot match the fire rate of a semi-auto like those in our Stevens 555 Sporting line. It is also a poor choice for home defense due to its limited capacity and relatively long overall length compared to a pistol-grip shotgun.

What's in the box?

You receive the shotgun, a 5-piece internal choke tube set (including Improved Cylinder, Modified, and Full tubes), and a choke tube wrench. The package does not include a hard case—only a cardboard box and foam inserts—so plan to spend $75-$150 on a suitable protective case for transport. A basic owner's manual and warranty card are included, but no cleaning kit or lubricant is provided.

Is the Mossberg Silver Reserve II Over/Under Shotgun worth it at $747.99?

At this price point, it represents solid value for a shooter seeking a classic, no-frills over/under in a low-recoil caliber for specific recreation. You are paying for a proven mechanical action, decent wood, and functional engraving, not for adjustable features or premium brand prestige. If your primary need is for a versatile, multi-gauge shotgun for competition, a used Browning Citori or Beretta 686 often provides better resale and more aftermarket support for a similar initial investment.

Pros & cons

What works

Weighs 6.8 lb — 1.2 lb lighter than a comparable 20-gauge over/under for easier carry.
Includes 5 choke tubes (IC, M, F, plus two specialty tubes) for pattern tuning without extra cost.
Generates only 7 ft-lbs of felt recoil — ideal for training new shooters or long range sessions.
26-inch barrel provides a 42.5-inch overall length for easy maneuverability in blinds or thick cover.

Trade-offs

Fixed 14-inch length of pull — requires professional gunsmith work (approx. $150+) for any adjustment.
No hard case included — expect to spend $75+ for adequate transportation protection.
Proprietary Accu-Choke threads — limits aftermarket choke tube options compared to industry-standard Mobilchoke.
.410 bore limits effective ethical range on game to under 30 yards due to low pellet count.
