Abstract: A firearm suppressor that includes a mount configured to connect the firearm suppressor to a barrel of a firearm. The firearm suppressor includes a first module connected to the mount. The interior of the first module is a first chamber and the first module does not include a baffle. The firearm suppressor includes a second module connected to the first module. The second module includes a plurality of baffles and at least one peripheral pathway that bypasses a second baffle of the plurality of baffles by fluidly connecting an exterior of a first baffle of the plurality of baffles with an exterior of an exterior of a third baffle of the plurality of baffles. The firearm suppressor includes an end cap connected to the second module.

Abstract: A cooling jacket assembly includes an inner housing and an outer housing. The inner housing is disposed within the outer housing. The inner housing and the outer housing define fluid channels therebetween. The inner housing is configured to receive a cell array therein. The inner housing is coupled to the outer housing. The cooling jacket assembly is configured to transfer heat from a heat transfer fluid through the inner housing to the cell array.

Abstract: An energy harvesting device for accurately counting rounds fired by a firearm comprises a piezoelectric element for mechanical coupling to the barrel of the firearm. The piezoelectric element may produce a voltage waveform in response to the mechanical vibrations from a round passing through the barrel, which may power a microcontroller. The microcontroller may determine the rate of change of the voltage waveform to determine if a live round was fired. The microcontroller may be in communication with an RFID chip. The microcontroller may read the value on the RFID chip, increment the value of the RFID chip in response to being turned on by the voltage waveform, and then store the incremented value on the RFID chip. An armorer may remotely check the value of the RFID chip.

Abstract: A hyper velocity firearm has a downwardly-hinging toggle action. The toggle action incorporates at least one coiled torsion spring that is incorporated in at least one pivot of the toggle. A first embodiment of the firearm employs two torsion springs. A second embodiment employs a single adjustable-tension torsion spring. Tension is adjustable without disassembly of the toggle mechanism. A third embodiment employs a horizontally-oriented compressible coil spring positioned above the toggle to bias the toggle. In the pre-discharge configuration, the toggle of the present invention is about 3 degrees from a straight angle linkage, with a negative degree angle representing an over-center condition. The toggle action is compact and reduces recoil and muzzle lift when the firearm is discharged.
