The Hydra is blowback operated, and the barrel employs non-progressive gain twist rifling. It currently has an unloaded weight of 9.91 lbs, and a OAL of 32.75 inches. It is rated for Rheinmetall-Waffen’s
40x46mm “magnum” rounds, as well as all
40x46mm low velocity rounds. It will be made in the USA. Some possible upgrades to the design before full production are modification of the safety and magazine release, as well as grips made out of something more durable like G10. Though the model pictured has an 8″ Barrel, the final barrel will be 10″. It will be compatible with many existing GL sights as well.
