The Cadex Kraken sits in its own proprietary chassis that combines design elements of the Dual Strike and the Light Strike chassis that is highly ergonomic and adaptable. At the rear of the Kraken’s chassis is a completely tool-less buttstock that is adjustable for length of pull, cheek piece height, and recoil pad height. The magazine well is designed to use interchangable magazine sleeves that accept most AICS pattern magazines. The chassis system features an over-the-action full length top rail that is available in 20, 30, or 45 MOA.
