US12624910 - Reduced weapon system blowback

A reloading firearm featuring a mechanism to reduce the blowback of toxic propellant gasses towards the warfighter.

US12618628 - Forged carbon fiber rifle barrel

A method of forming a carbon fiber rifle barrel may include the steps of heating a barrel core to increase the length of the barrel, placing the barrel core inside a mold and holding the lengthened barrel in place, adding a carbon fiber mix to the mold in which the carbon fiber mix includes a blend of resin and chopped carbon fibers, sealing the mold, curing the carbon fiber mix surrounding the lengthened barrel core in which the cured carbon fiber mix holds the length of the barrel core creating a tension on the cooled barrel core which increases a rigidity of the rifle barrel thereby increasing the accuracy of the rifle barrel, removing the rifle barrel from the mold, and finishing the rifle barrel via grinding to a desired finish.

US12618629 - System for cooling automatic firearms and cannons

A barrel cooling system for a weapon includes a corrosion prevention cylinder between a barrel and cooling fins arranged around the cylinder.

US12618630 - Modular firearm suppressor

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.

US12618631 - Suppressor

A suppressor assembly is disclosed. The suppressor can comprise an outer tube defining a barrel axis, a first endcap configured to couple to a barrel of a firearm at a first end of the outer tube, and a spacer assembly in the outer tube. The spacer assembly can be positioned and/or captured between the first endcap and an exit side of the outer tube. The spacer assembly can comprise a plurality of spacers comprising a plurality of small and large diameter baffles oriented in different desirable positions within the spacer assembly. The baffles and spacers can be constructed from different materials so the weight of the baffles are greater than the weight of the spacers.

US12618632 - Off-axis serpentine flow chamber for firearm suppressors

A firearm sound suppressor can include an outer housing that defines a bore axis and an inner wall disposed at least partially within the outer housing. The inner wall can be oriented along the bore axis and includes a cylindrical central chamber. An annular chamber can be disposed between the outer housing and the inner wall. At least one helical partition can be disposed in the annular chamber to define at least one interleaved helical pathway through the annular chamber. Each interleaved helical pathway includes a first forward helical segment, a reverse helical segment sharing a first common wall with the first forward helical segment, and a second forward helical segment sharing a second common wall with the reverse helical segment. The first and second common walls can be distinct from one another.
