Citadel BOSS-25 12 Gauge USA Flag Semi-Auto
About this product
The Citadel BOSS-25 12 Gauge USA Flag Semi-Auto is a gas-operated, tactical shotgun built for configurability and durability, featuring a distinctive American Flag Cerakote finish, an adjustable synthetic stock with a cheek riser and pistol grip, and a receiver-integrated Picatinny rail. This model prioritizes modular control over traditional sporting aesthetics, shipping with five internal choke tubes (Improved Cylinder, Modified, Full, Extra Full, and a dedicated turkey tube), a threaded 18.5-inch chrome-lined barrel, and a factory-installed muzzle brake designed to reduce felt recoil by an estimated 30% compared to an uncompensated barrel of similar length and profile. At 8.0 lbs unloaded and with an overall length of 38 inches, it occupies a niche between dedicated home-defense shotguns and multi-purpose field guns.
What is the Citadel BOSS-25 used for?
The Citadel BOSS-25 is used for dynamic shooting situations requiring fast follow-up shots and accessory adaptability, including defensive training, 3-Gun competition in the limited division, and tactical shotgun courses. Its gas-operated semi-automatic action reliably cycles a wide range of 12-gauge loads from 2 ¾-inch target loads up to 3-inch magnum shells, while the adjustable stock and multiple choke tubes allow the user to tailor the shotgun's fit and shot pattern for steel, slugs, or birdshot. For a more traditional application focused purely on clays or field hunting, consider the Stevens 555 Sporting O/U 12 Gauge, which offers superior pointability for swing-through shots.
How does the Citadel BOSS-25 compare to the Stevens 334 Rifle?
The Citadel BOSS-25 provides rapid, close-range terminal ballistics and modularity via its rail system and threaded barrel, while the Stevens 334 Rifle in .308 Win is superior for precise, deliberate engagement at extended ranges. The BOSS-25's action can handle multiple projectiles (shot) and single projectiles (slugs) interchangeably with a simple choke change, whereas the bolt-action Stevens 334 is dedicated to a single projectile type, offering significantly greater accuracy past 100 yards but with a much slower rate of fire. The BOSS-25 is the tool for breaching, room clearing, or fast-paced sport shooting where rapid target engagement is key; the Stevens 334 is for hunting or precision shooting where one well-placed round is the objective.
What does it weigh and what are the dimensions?
The Citadel BOSS-25 weighs 8.0 lbs (128 oz) unloaded and measures 38 inches in overall length with its 18.5-inch threaded barrel; with the stock fully collapsed, the length of pull is adjustable from 13.5 to 15.7 inches to accommodate different body armor or clothing setups. The receiver features an integrated 11-slot Picatinny rail section for mounting optics or red dots, and the 1.5-inch diameter magazine tube has a capacity of five 2 ¾-inch shells, giving you a total on-board capacity of 6 rounds (5+1) before reloading, which is standard for this class of tactical shotgun.
Who is this NOT for?
This shotgun is not for traditional upland hunters or trap/skeet purists who prioritize lightweight carry, graceful swing, and classic aesthetics, as its 8.0 lb weight and tactical stock profile are not conducive to all-day walks through fields. It is also not ideal for beginners seeking their first general-purpose shotgun, as its tactical features and focus on accessory rails may be superfluous compared to a simpler pump-action or field semi-auto, which would be more versatile as a singular tool for hunting, home defense, and clays. Individuals in states or municipalities with restrictions on pistol-grip shotguns or threaded muzzle devices must verify local compliance before purchase.
What's in the box?
Inside the box, you will find the Citadel BOSS-25 shotgun with its American Flag Cerakote finish applied to the receiver and barrel, a set of five internal choke tubes housed in a plastic keyed container (Improved Cylinder, Modified, Full, Extra Full, Turkey Tube), a factory-installed muzzle brake, and a single 5-round magazine tube plug for migratory bird hunting compliance. A basic owner's manual covering disassembly and warranty registration is included, but notably absent are tools for choke tube removal or any rail-mounted accessories, which must be sourced separately to utilize the platform's full modular potential.
Is the Citadel BOSS-25 worth it at $405.99?
At $405.99, the Citadel BOSS-25 is worth it for the shooter who specifically needs a dedicated tactical/competition platform with an out-of-the-box feature set that would otherwise require aftermarket upgrades, such as the adjustable stock, rail, and muzzle device. You are paying for functional configurability and a durable Cerakote finish, not for a finely finished walnut stock or hand-fitted mechanical tolerances found on shotguns costing three times as much. For this price point, its direct competitor is often a basic Mossberg 500 or Remington 870 pump-action in a field configuration; the BOSS-25's semi-automatic action and included features represent a measurable performance advantage in speed and recoil management for the same financial investment.

Pros & cons
What works
- Gas-operated semi-automatic action reliably cycles 2 ¾-inch to 3-inch shells, minimizing felt recoil compared to inertia-driven systems.
- Adjustable synthetic stock offers a 2.2-inch length of pull range (13.5" to 15.7") for fitment with body armor or winter clothing.
- Includes 5 internal choke tubes (IC, M, F, XF, Turkey) and a muzzle brake, a $75-100 value if purchased separately.
- Receiver-integrated 11-slot Picatinny rail provides a solid base for optics without requiring a separate mount.
Trade-offs
- Proprietary choke tube system limits aftermarket options; replacements must be sourced from Citadel.
- No iron sights are included—you must supply your own optic or ghost ring set for the rail, adding $50-300 to total cost.
- The American Flag Cerakote finish, while durable, is visually conspicuous and not suited for tactical concealment or traditional hunting applications.
- At 8.0 lbs, it is 1.5-2 lbs heavier than many field-oriented semi-autos like the Mossberg 930, affecting maneuverability.

Frequently asked questions
- Is it compatible with standard Beretta/Benelli Mobil choke tubes?
- No, the Citadel BOSS-25 uses a proprietary internal choke tube system; it is not compatible with industry-standard Beretta/Benelli Mobil choke tubes. The provided set of five tubes (IC, M, F, XF, Turkey) covers a variety of patterning needs, but replacement or specialty tubes must be sourced directly from Citadel. The choke tube wrench slot requires a ¾-inch standard choke wrench or a large, flat-headed coin for removal.
- Does it fit in a standard 42-inch rifle case?
- Yes, with the stock adjusted to its shortest length of pull (13.5 inches), the BOSS-25's 38-inch overall length will fit comfortably in a standard 42-inch soft or hard rifle case. Be mindful that the factory muzzle brake adds approximately 2.5 inches to the front profile; a case with a 44-inch interior compartment is recommended if you intend to transport it with the brake installed to prevent snagging on the interior lining.
- How long does shipping take?
- Shipping for firearms typically involves a 1-3 business day processing time after FFL verification, followed by ground freight transit of 3-7 business days depending on your location relative to our warehouse. All shipments are made via UPS or FedEx with adult signature required upon delivery to your selected, licensed FFL dealer. Please allow 7-10 total business days from order confirmation to FFL arrival.
- Can I return it if it doesn't fit?
- Due to federal regulations, firearms cannot be returned after transfer is completed at your FFL dealer; all sales are final once the firearm is received by the licensee. We strongly recommend you physically handle a similar model at a local dealer or confirm the adjustable stock's 13.5 to 15.7-inch length of pull range will suit your needs before ordering. If the firearm arrives damaged or defective, contact us within 72 hours of FFL pickup to initiate a manufacturer warranty claim.
- Does this work with a Magpul SGA stock?
- No, the Citadel BOSS-25 uses a proprietary mounting interface for its synthetic stock with integrated cheek riser; it is not compatible with the popular Magpul SGA stock system designed for Mossberg and Remington shotguns. Aftermarket stock options for the BOSS-25 are limited, so ensure the factory stock's adjustment range and pistol grip angle are acceptable for your intended use before purchase.
- Is the barrel threaded for choke tubes or for a suppressor?
- The barrel is internally threaded at the muzzle end to accept the included choke tubes; it is **not** externally threaded to accept a suppressor or direct-thread muzzle device like a 12-gauge shotgun silencer. The muzzle brake screws onto external threads that are part of the choke tube assembly itself. For suppressor compatibility, you would need a barrel with external threading and a compatible choke tube adapter, which is not standard on this model.
