  • Firearm with integrated power source
    Patent number: 10088269
    Abstract: A firearm is described that includes an integrated power source, socket, and conductor connecting the power source to the socket. By integrating these elements into a firearm, a powered accessory can be attached to the firearm without the need for a mounting rail attached to a firearm. Furthermore, powered accessories need not have their own integrated power sources, but rather can connect to the power source within the firearm. This reduces the weight and physical dimensions of both firearms and accessories.

  • MACHINE GUN SUPPRESSOR
    Publication number: 20230417507
    Abstract: A suppressor for a firearm includes a baffle stack having an outer surface, the baffle stack comprising a plurality of baffles that define an inner chamber extending along a central axis of the baffle stack and a projectile pathway through the baffle stack along the central axis. An outer housing is around the baffle stack and defines an outer volume between the outer housing and the baffle stack. Structures and openings in the suppressor promote a sinuous gas flow path through the inner chamber that enhances turbulent flow within the suppressor and reduces backpressure as desirable when used with a machine gun.
