Detachable rotary magazine is incorporated into the X-Bolt. Constructed from a durable lightweight polymer, the magazine is designed to feed cartridges directly in-line with the bolt, instead of offset as with traditional leaf-spring magazines, for a straight shot right into the chamber. An ergonomic magazine-mounted release lets the magazine rotate directly downward and into the hand. The magazine sits flush with the bottom of the rifle for a sleeker appearance. Additional magazines can be kept loaded and carried for easy access. Magazines are designed to handle multiple calibers.
