This Generation 2 model features the highly upgraded, completely flat-top receiver and dual ambidextrous side-charging handles, fixing the ergonomics of the older Gen 1 versions. By placing the action behind the trigger group, this bullpup packs a full-length 20-inch chrome-lined barrel into a remarkably short, highly maneuverable 30.7-inch overall length. It is an incredibly fast-handling, compact firearm perfect for home defense, tactical training, or range day fun. The shotgun features a rugged 7075-T6 aluminum upper receiver and an ergonomic synthetic lower with an integrated, adjustable cheek riser. It has a standard 3-inch chamber and a reliable gas-piston system designed to cycle both 2 3/4" and 3" heavy loads and buckshot smoothly.
