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.

Abstract: The invention provides a system and method for intercepting a target UAV by releasing a plurality of countermeasure (CM) objects in a projected path thereof to form a 3D countermeasure cloud. Pieces of flexible materials configured to become ensnared in the propellers of the target UAV or otherwise interfere with their ability to provide lift and thrust capabilities to the UAV. A UAV interception control system may track the target UAV and compute a location probability volume therefor using a modified Kalman filter to decide on a projected interception location and time.

Abstract: A fixed-to-tilted silencer adaptor for three-lug attachments enables the use of tilting barrel gun silencers or fixed non-moving barrel gun silencers with different guns of the same caliber. The present invention enables users to utilize a gun silencer with the desired gun even if the gun silencer does not match the design of the gun. To do so, the present invention may comprise a recoil booster and a three-lug adaptor. The recoil booster is designed to accommodate the movement of a tilting barrel while facilitating the connection between the gun silencer and the gun's barrel. The recoil booster also securely receives the three-lug adaptor to facilitate the quick attachment of the recoil booster to the gun's barrel. The three-lug adaptor is designed to enable the quick attachment of the recoil booster to the gun's barrel without interfering with the movement of the gun's barrel when connected to a tilted barrel.
