The B.Mag Sporter was built around the 17 Win. Super Magnum cartridge, which creates unprecedented rimfire velocities of up to 3,000 feet per second. To make the most of the load’s potential, we gave the rifle features usually reserved for centerfires, such as an action with rear locking lugs, a cock-on-close bolt, thread-in barrel headspacing and a center-feed rotary magazine. The B.Mag Sporter also has a striking wood laminate stock and the game-changing AccuTrigger™, which shooters can safely adjust for a light, clean pull.
