The X-Bolt uses a detachable rotary magazine constructed from a durable lightweight polymer. The magazine feeds cartridges directly in line with the bolt, instead of o set as with traditional leaf-spring magazines, for a straight path right into the chamber. An ergonomic magazine-mounted release lets the magazine rotate directly downward and into the hand. Additional magazines can be kept loaded and carried in a pocket or pack for easy and safe access.
