  • Patent number: 10857580
    Abstract: A method and apparatus for producing gun barrels having a grooved or ribbed inner surface with straight or helical grooves or ribs, by providing a metallic hollow cylindrical pre-form, placing the pre-form on a core mandrel being part of a flow forming machine having a main machine axis, the core mandrel having a structured outer surface comprising ribs and/or grooves extending straightly parallel to and/or helically around the main axis; and applying forming rollers, in a roller arrangement, to the outside surface of the pre-form so as to apply radial pressure on the pre-form such that its material begins to flow. As the rollers apply force upon the pre-form, a relative motion between the pre-form and the rollers is performed by moving the pre-form in axially parallel to the main axis through the roller arrangement or by moving the roller arrangement alongside the pre-form.

  • Patent number: 10859334
    Abstract: Systems for universally locking a trigger of a firearm are provided that require authentication to transition the firearm to an unlocked state. In general, examples of the systems for universally locking a trigger of a firearm described herein are located in an interchangeable grip portion of the firearm or mounted to an accessory rail of the firearm. Embodiments of the system generally include trigger interference or blocking members to prevent actuation of the trigger until the authentication system has authorized the user to fire the firearm. Once the system is authenticated, embodiments of the system remain in an unlocked state while the user is grasping the firearm. When the user removes their hand from the firearm, embodiments of the trigger locking system automatically returns to a locked state, reducing or eliminating unauthorized use of the firearm.
