Pros & cons

What works

  • Factory-threaded 0.825"-24 barrel — ready for suppressors without $150+ gunsmithing
  • Two 5-round steel magazines included — $90 value compared to aftermarket
  • Weighs 7.6 lbs empty — 1.2 lbs lighter than the comparable Panzer M4
  • Includes 5 choke tubes (F, IM, M, IC, C) — covers patterning from 5 yards to 45+

Trade-offs

  • Requires a 200-round break-in period with full-power loads for reliable cycling — budget $75+ for ammunition
  • Synthetic stock has minimal cheek weld — adding a pad increases height-over-bore by 0.5 inches
  • Magazine release is stiff — requires a deliberate 4.5 lb press force, not conducive to fast reloads initially

Expert review

I ran 500 rounds through the BOSS-25 over three weekends at my range outside Bozeman, specifically testing its reliability with mixed loads and its performance suppressed with a SilencerCo Salvo 12. The first detail you notice is the mechanical resonance; the action cycling has a distinct, solid clack that echoes more than a typical inertia-driven semi-auto. After the first 200 rounds of Federal FliteControl 00 buck, the gas system settled in and reliably fed everything from light 1-ounce target loads to 3-inch magnum slugs without adjustment—a notable point for a budget platform. Compared directly to the Turkish-made Panzer M4, which retails for about $425, the BOSS-25 is 1.2 pounds lighter and ships with twice the number of magazines. Where the Panzer uses a more complex dual-gas-piston system, the BOSS-25 employs a simpler single-piston design that is easier to clean but can be slightly more sensitive to underpowered ammunition. In rapid-fire drills, the BOSS-25's 0.2-second split time was consistently 0.05 seconds faster than the Panzer, likely due to its lighter reciprocating mass. The honest weakness is the magazine system. The magazines fit tightly and require a firm, practiced slap to seat on a closed bolt. During a timed drill in 40-degree weather, I experienced two failure-to-feeds directly attributable to the magazine lips not presenting the shell at the correct angle; this disappeared when I lubricated the mag lips with a dry film lubricant. The manual makes no mention of this need, and it's a critical oversight for a duty-oriented gun. Buy this if you need a suppressor-host shotgun or value magazine-swap drills, and you're willing to invest the break-in ammunition. Skip it if you want a simple, out-of-the-box reliable pump-action for the closet, or if you live in a magazine-restricted state—the 5-round mags are a compliance problem. For $355, it delivers legitimate tactical utility that usually costs hundreds more to build, but you trade some initial refinement for that capability.

About this product

The Citadel BOSS-25 is a 12 gauge semi-automatic tactical shotgun built for adaptable duty and defensive applications. It represents one of the few sub-$400 platforms offering both a factory-threaded barrel for suppressors and the logistical flexibility of detachable box magazines. The design prioritizes administrative handling—the 5+1 capacity is dictated by federal law for imported shotguns—while the included choke system and adjustable sights provide meaningful configuration options right from the unboxing.

What is the Citadel BOSS-25 used for?

The BOSS-25 is engineered for home defense, law enforcement patrol vehicle duty, and as a modular range gun for shooters understanding NFA compliance. This is not a hunting shotgun, despite the included choke tubes; its 18.5-inch barrel (the exact length of 470 mm) and tactical furniture make it purpose-built for dynamic engagement scenarios. Its gas-operated action handles everything from light 2¾-inch target loads to 3-inch magnum buckshot, with a cyclic rate I clocked at approximately 0.2 seconds between shots during controlled pairs on steel.

How does the Citadel BOSS-25 compare to the Stevens 555 Sporting O/U Shotgun?

The BOSS-25 is superior for tactical versatility, while the Stevens 555 Sporting O/U 12 Gauge is better for recreational clay shooting and smooth presentation. Where the Stevens 555 is a dedicated break-action sporting gun with fixed chokes and traditional wood stock, the BOSS-25 offers magazine swaps and accessory mounting on its Picatinny top rail. For defensive use or training that involves administrative reloads, the BOSS-25’s detachable magazines provide a tangible advantage the break-action design cannot match.

What does it weigh and what are the dimensions?

Empty, the BOSS-25 weighs 7.6 pounds (3.45 kg), with an overall length of 39.2 inches (995 mm). The weight is forward-biased due to its steel barrel assembly and muzzle device, which provides some felt recoil mitigation but makes one-handed manipulation clumsy. Collapsing the synthetic stock reduces the length by 5.1 inches (130 mm)—a critical difference for vehicle storage or tight-quarters maneuvering compared to a fixed-stock shotgun.

Who is this NOT for?

This shotgun is not for the budget-conscious buyer looking for a simple pump-action for occasional use. It’s a semi-automatic platform with specific lubrication points and a disassembly sequence more complex than a Mossberg 500. It is also not for buyers in states with magazine capacity restrictions; its 5-round magazines are non-compliant in jurisdictions like California without permanent modification. New shooters or those unwilling to invest in spare magazines ($45-60 each) should consider a tube-fed model.

What's in the box?

The package includes the shotgun, two 5-round steel magazines, a set of five choke tubes (Full, Improved Modified, Modified, Improved Cylinder, Cylinder), a choke tube wrench, and a basic owner's manual. The manual lacks detail on gas system adjustment—a notable omission. Each magazine weighs 13.4 ounces (380 grams) when fully loaded with 2¾-inch shells, adding significant heft to a loaded kit.

Is the Citadel BOSS-25 worth it at $354.99?

At $354.99, the BOSS-25 is worth the price for buyers needing a threaded barrel and magazine system without custom gunsmithing. The Cerakote finish and included choke array alone represent about $120 in aftermarket value. You are paying for configuration, not refinement; the action benefits from a 200-round break-in period with full-power loads. For comparison, converting a standard pump-action shotgun to accept detachable magazines and adding threading typically costs more than this shotgun's total price, making this an efficient entry into modular tactical platforms.

Frequently asked questions

Is it compatible with standard shotgun chokes?
Yes, the BOSS-25 uses standard Beretta/Benelli Mobil-style choke tubes with a 22mm wrench flat. The included set covers constrictions from Cylinder (0.725 inches) to Full (0.695 inches). Aftermarket chokes from brands like Carlson's or Trulock will thread directly into the factory barrel.
Does this work with a Salvo 12 suppressor?
Yes, the barrel is threaded 0.825"-24 TPI, which is the standard for many 12-gauge suppressors including the SilencerCo Salvo 12. You will need to verify that your chosen choke tube is compatible, as some suppressors require a specific choke or direct-thread attachment. Always consult your suppressor manufacturer for exact mounting specs.
How long does shipping take for an online-only firearm?
Firearm shipments typically take 3-7 business days to reach your designated FFL dealer after order processing. The transfer must be completed in person with a background check, which can add 1-5 days depending on state laws and dealer workload. Ironclad Armory ships via FedEx with adult signature required.
Can I return it if it has a mechanical issue?
Mechanical defects are covered by a 1-year manufacturer's warranty handled directly by Citadel. Returns must be initiated within 30 days of purchase and the firearm must be shipped by a licensed FFL. Expect a 4-6 week turnaround for warranty inspection and repair; photographic evidence of the issue is required to initiate the process.
Does this fit in a standard rifle case?
With the stock collapsed, the BOSS-25 fits in a 36-inch rifle case, like the Plano All-Weather 36". At full length, it requires a 42-inch case. The width with magazines inserted is 3.2 inches, so ensure your case's internal foam can accommodate that profile without compressing the sights.
Is the muzzle brake removable for suppressor use?
Yes, the factory-installed muzzle brake unscrews using a ¾-inch wrench, exposing the 0.825"-24 threads. Apply a small amount of anti-seize compound to the threads before installing a suppressor mount, and torque to 15-20 ft-lbs. The brake itself adds 2.8 ounces and 1.5 inches to the overall length.
