The A400 action is truly revolutionary in the history of the semiautomatic shotgun. With Beretta's proprietary Blink technology, it shoots 36% faster than any other system, meaning that your follow-up shots will always be faster than any turkey, deer, duck or clay target. Thanks to its 3½" chamber, it can fire any type of 12 gauge shell, giving the A400 the versatility of a do-it-all shotgun. The Kick-Off Mega system reduces recoil by up to 70%. The Optima-Bore HP configuration offers the best ballistic performance available, even with steel shot. The Micro-Core recoil pad is softer and lighter than rubber and expands its surface area on the shoulder for secure and precise support. This model has a Realtree Max-5 camo finish. Every A400 Xtreme Unico KO comes with a dedicated case with stock drop spaces, Beretta oil, quick detachable swivels, and three choke tubes with a wrench.
