A detachable rotary magazine is incorporated into the X-Bolt, Browning’s latest bolt-action rifle. 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 path 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 in a pocket or pack for easy and safe access. Magazines are designed to handle multiple calibers to simplify ordering and inventory.
