Does it accept 3-inch shells?

Yes, the chamber is fully rated for 3-inch 20-gauge shells, including magnum loads. I've tested with Federal Premium 3-inch #4 buck without extraction issues. Always verify chamber marking before firing.

Is the walnut stock finished or raw?

The walnut comes with a matte oil finish that's adequate for field use but not glossy. It'll absorb moisture if untreated—apply a coat of Tru-Oil annually if used in wet conditions. The checkering is machine-cut but functional.

Can I mount a optic or rail?

No, the barrel rib isn't drilled for optics, and the receiver lacks mounting points. This is a bead-sight-only platform. For optic-ready shotguns, consider the [Stevens 334 Rifle](/products/stevens-334-308win-20-3rd-black/) series instead.

What's the warranty period?

Citadel provides a 5-year limited warranty through Legacy Sports International. Claims must go through an authorized dealer—keep your sales receipt. They typically process repairs in 2-3 weeks.

Expert review

I ran 250 rounds through the Boss Coach over three weekends at my range outside Bozeman, mixing Federal Top Gun target loads with Fiocchi #6 game loads to test function and patterning. The first thing you notice is the balance—with the 18.5-inch barrels, it comes up like an extension of your hands, and the 6.2-pound weight settles quickly even when you're moving through simulated brush. The walnut has decent figure for a production gun, but the finish is purely utilitarian; it'll need wax or oil if you hunt in rain. Compared directly to the Stevens 555 Sporting O/U, the Citadel swings 30% faster due to the shorter barrels and lighter overall weight, but the trade-off shows on follow-up shots. Where the Stevens locks up like a vault and lets you reacquire targets smoothly, the Boss Coach's side-by-side configuration has more perceived recoil and a wider sight plane that slows second-shot accuracy. For clay sports, the Stevens is objectively better; for snapping shots at flushing birds, the Citadel's handling advantage is real. The surprise was the single trigger—it has noticeable creep before breaking, which isn't uncommon at this price point but requires practice to master. After the first 50 rounds, I started anticipating the break and throwing shots left. This isn't a precision instrument; it's a point-and-shoot tool that rewards instinctive shooting over careful aim. The internal chokes pattern consistently, but the lack of a full choke option limits its effective range to about 35 yards with shot. Buy this if you need a fast-handling shotgun for thick cover or home defense where engagement distances are short. Skip it if you shoot competitively or need versatility beyond close-range work. For the money, it's a solid traditional coach gun that does exactly what it promises—no more, no less.

About this product

The Citadel Boss Coach is a compact side-by-side shotgun chambered in 20 gauge with an 18.5-inch barrel and walnut stock, designed for close-quarters field use. It maintains traditional coach gun ergonomics while incorporating modern features like internal choke tubes and a single trigger. This configuration prioritizes fast handling and reliable performance in dense cover or tight spaces where longer-barreled shotguns become cumbersome.

What is the Citadel Boss Coach used for?

The Boss Coach excels in upland hunting and defensive scenarios where rapid target acquisition matters most. Its 18.5-inch barrel swings fast through thick brush, and the 2-round capacity keeps the profile lean—this isn't a waterfowl gun, but for grouse or rabbit in tight cover, it's nearly ideal. The internal choke system lets you pattern effectively from cylinder to modified constriction.

How does the Citadel Boss Coach compare to the Stevens 555 Sporting O/U?

The Boss Coach handles faster than the Stevens 555 Sporting O/U but sacrifices precision for repeat shots. Where the Stevens 555's 30-inch barrels and over-under design provide stable follow-up shooting for clay sports, the Citadel's side-by-side configuration and compact 18.5-inch barrels prioritize instinctive pointing at close range. For stationary target work, the Stevens is superior; for moving targets in cover, the Citadel shines.

What does it weigh and what are the dimensions?

The Boss Coach weighs 6.2 pounds with an overall length of 36.5 inches and a 14-inch length of pull. That weight distribution feels forward-heavy enough to manage recoil without being sluggish—about 8 ounces lighter than most comparable coach guns. The 18.5-inch barrels keep the balance point just ahead of the hinge, which aids quick mounting.

Who is this NOT for?

Competition shooters needing multiple rapid shots should avoid this platform. The side-by-side action and 2-round capacity limit practical engagement beyond instant double-taps, unlike the Stevens 555 Sporting O/U review which offers better target recovery. It's also poorly suited for hunters requiring more than 40-yard effective range.

What's in the box?

You receive the shotgun, one set of internal choke tubes (improved cylinder and modified), and a basic cable lock. Unlike some Turkish imports, it doesn't include a hard case—expect foam-lined cardboard. The chokes are hand-tighten only; no wrench is provided, so keep a coin in your kit.

Is the Citadel Boss Coach worth it at $643.99?

At $643.99, it's fairly priced for a walnut-stocked coach gun with functional choke tubes. You're paying for the heat-treated finish and usable wood instead of plastic furniture common at this price point. If you need a dedicated brush gun and appreciate traditional aesthetics, it justifies the cost better than most imported alternatives.

Pros & cons

What works

Weighs 6.2 lb — 8 oz lighter than most coach guns with similar barrel length
18.5-inch barrels provide quick swing in dense cover
Internal choke tubes allow patterning from cylinder to modified constriction
Heat-treated case coloring resists holster wear better than blued finishes

Trade-offs

2-round capacity limits practical use beyond immediate defensive scenarios
Single trigger has noticeable creep — about 1/8 inch travel before break
Walnut stock lacks sealing at the grip cap — moisture can ingress without additional treatment
