The Frankford Arsenal M-Press Coaxial Reloading Press is designed to handle the stress of the reloading room. With a die-cast construction, this rugged press features a floating shell holder that allows for dynamic positioning. The square clamps are spring loaded with different case size recesses that allow you to use small, medium, large or magnum sized cases without the need for individual shell holders. Set your dies and know they are locked in place with the Frankford Arsenal Die Block Kit. With an aluminum construction and an allen set, all three die blocks can be set and stored without worry of them getting moved. The included storage case is stackable making for easy organization and the box features a hinge-top lid to ensure durability.
