Beretta A400 Xtreme Unico KO 12 Gauge 28" Semi-Auto Shotgun, 3 ½" Chamber, Kick-Off Stock
The Beretta A400 Xtreme Unico KO is purpose-built for demanding waterfowl and upland hunters who need a 12 gauge that cycles everything from light 2 ¾" loads to heavy 3 ½" magnums. Its Steelium tri-alloy barrel, BLINK gas system, and Kick-Off hydraulic recoil modules combine to deliver quick follow-up shots with reduced felt recoil, even in harsh environments. This example shows honest field use but still offers the fast cycling, corrosion resistance, and tool-less takedown that make the A400 Xtreme series a go-to choice in tough conditions.

What’s Included
- Beretta A400 Xtreme Unico KO 12 Gauge shotgun
The 28" Steelium barrel is paired with Beretta’s Optima-Bore HP choke system and a 12F choke, giving the shooter flexibility and even patterns with steel or lead shot. A ventilated rib and green fiber-optic front bead provide a clear sight picture in low light.
Beretta’s BLINK gas system uses a self-cleaning piston and a light bolt assembly to cycle shells up to 36% faster than traditional gas guns. Combined with the corrosion-resistant nickel-Teflon-coated carrier and sealed receiver, the A400 Xtreme stays reliable in mud, rain, and saltwater.
The Unico platform’s 3 ½" chamber accepts 2 ¾", 3", or 3 ½" shells without adjustment, making this shotgun a single-gun solution for everything from doves to geese. A 2+1 capacity keeps the overall package light while meeting many migratory bird regulations.
Recoil is tamed by the Kick-Off hydraulic modules in the glass-fiber-reinforced polymer stock and a soft Micro-Core recoil pad. Even though the stock on this unit is damaged, its design highlights why these shotguns are known for manageable recoil, fast target reacquisition, and all-day shootability.
