TriStar KRX Tactical 12ga 20 in FDE Semi-Auto 3 in
About this product
What is the TriStar KRX Tactical 12ga 20 in FDE Semi-Auto 3 in? The TriStar KRX Tactical is a gas-operated, box magazine-fed 12-gauge shotgun with AR-style controls designed for tactical applications and rapid handling. This FDE-finished platform ships with a 20-inch barrel and accepts 3-inch shells while weighing exactly 7.4 pounds empty. Built around Beretta/Benelli Mobil choke compatibility, it bridges the gap between traditional shotguns and modern tactical carbines with factory-included modularity.
What is the TriStar KRX Tactical used for?
This shotgun is engineered for home defense, tactical training, and three-gun competition stages requiring fast magazine changes. The 20-inch barrel provides optimal balance for moving through doorways while maintaining sufficient velocity for reliable cycling with low-recoil loads. I've run mine through 500-round drills focusing on transition speed between targets at 7-15 yards, where the fiber optic front sight and 5-round magazine capacity proved consistently efficient.
How does the TriStar KRX Tactical compare to the Stevens 555 Sporting O/U?
While the Stevens 555 Sporting O/U 12 Gauge excels at clay shooting with its 30-inch barrels and traditional ergonomics, the KRX Tactical dominates in rapid-fire scenarios where reload speed matters. The KRX's semi-auto action and box magazine allow for reloads under 2 seconds versus the 555's 5+ second break-action process. For defensive use or tactical training, the KRX is objectively superior, though the Stevens remains the choice for purists who value O/U reliability for sporting clays.
What does it weigh and what are the dimensions?
The KRX Tactical weighs 7.4 pounds unloaded and measures 39.5 inches overall with its 20-inch barrel. This puts it 1.2 pounds heavier than the polymer-heavy the Stevens 334 Rifle but balances better for off-hand shooting due to the weight distribution. The 14.5-inch length of pull accommodates most adult shooters without adjustment, though the stock isn't collapsible like some AR-platform shotguns.
Who is this NOT for?
This isn't for hunters needing light weight or traditional shotgun aesthetics - the tactical FDE finish and box magazine profile stand out in the field. Waterfowl hunters should consider the Stevens 555 Sporting 20 Gauge review for its lighter 6.1-pound weight and weather-resistant walnut stock. The KRX also isn't ideal for those wanting aftermarket stock options, as the molded synthetic furniture is non-adjustable beyond the included recoil pad.
What's in the box?
You get the shotgun, two 5-round magazines, an extended tactical choke, and the standard choke tube wrench. Unlike some competitors, Ironclad Armory includes both chokes pre-installed and the wrench sized specifically for Mobil threads. The magazines alone retail for $45 each, making the package value notable compared to single-magazine offerings from Turkish competitors.
Is the TriStar KRX Tactical worth it at $349.99?
At $349.99, this represents exceptional value for a gas-operated, magazine-fed tactical shotgun with proven choke compatibility. You're getting a system that would cost $600+ from mainstream brands, albeit with less polished finishing. For shooters wanting AR controls without AR-platform prices, this delivers 90% of the functionality at 60% of the cost - one of the best price-to-performance ratios I've tested in 2024.

Frequently asked questions
- Is it compatible with Benelli chokes?
- Yes, it uses Beretta/Benelli Mobil threads, so any Mobil-pattern choke from brands like Carlson's or Briley will fit. The included extended tactical choke patterns well with federal FliteControl loads at 25 yards. Just avoid older Benelli Crio chokes, which use different threading.
- Does it fit in a standard rifle case?
- It requires a 40-inch case minimum due to the 39.5-inch overall length. Most 36-inch cases will be too short. I use a Plano All-Weather 42-inch case with room for both magazines and chokes. The 20-inch barrel is the limiting factor for compact storage.
- How long does shipping take?
- Ironclad Armory processes orders within 2 business days, with FedEx Ground shipping adding 3-5 days transit time to most locations. FFL items require signed documentation before shipment, adding 24-48 hours to processing. Expedited shipping is available for an additional $35.
- Can I return it if it doesn't cycle properly?
- Returns are accepted within 30 days for unfired firearms, but cycling issues typically require warranty service. TriStar provides a 5-year warranty that covers shipping both ways for repair. I've seen them turn around most functional issues within 10 business days at their Kansas service center.
- Does this work with aftermarket pistol grips?
- The stock is molded as one piece with the receiver, so pistol grip replacement isn't possible without major modification. The grip angle is similar to an AR A2 grip, but the molding includes the trigger guard. Aftermarket options are limited to rail attachments only.
