Abstract: A firearm accessory and an end cap useful with the firearm assembly. The firearm assembly handles exhaust gas expelled with a round fired from a firearm and includes a fitting, a sleeve, a fluid pressure dissipation structure, and an end cap assembly located at a distal end of the fluid dissipation structure. The sleeve defines an internal volume that at least partially receives the fluid dissipation structure. The end cap assembly and the fluid dissipation structure at least partially define one or more distal chambers in communication with the internal volume. The end cap assembly defines an angled port.

Abstract: Provided is a modular firearm muzzle device having a multi-piece housing assembled from a plurality of substantially tubular, axially assemblable wall members that have a first interior cross-sectional size. A mounting member is mountable to a firearm muzzle. A forward wall has a central passageway that is aligned with the firearm muzzle and has a cross-section size smaller than the first cross-sectional size. The wall members are assembled with the mounting member and forward wall to define an interior chamber through which a projectile passes from the muzzle. The device can be assembled with fewer or more wall members to adjust the length of the interior chamber.

Abstract: A suppressor for reducing muzzle flash during firing of a firearm. The suppressor includes an auto purge channel configured to direct gas to a distal end of the suppressor adjacent an exit point of a projectile. In one example, the auto purge channel enables gas to saturate an area of the suppressor in front of the projectile. For example, the auto purge channel directs gas to the distal end of the suppressor at a speed that is greater than a speed of the projectile. In another embodiment, the projectile travels through combustion gasses transferred by the auto purge channel to reduce muzzle flash. In yet another example, the auto purge channel runs parallel to a central bore of the suppressor.

Abstract: Disclosed herein are suppressors for use with firearms or the like, and methods of making and using such firearm suppressors. Some aspects relate to a firearm suppressor including a helical portion extending helically around a cylindrical body portion, at least a section of the helical portion being canted such that it extends radially outward from the cylindrical body portion at an oblique angle relative to a plane normal to the central longitudinal axis. In some cases, the helical portion is canted distally.
In another respect, a firearm suppressor including a helical portion extending radially outward from and helically around a cylindrical body portion having a bore to define a crest and a root, and at least one channel extends from an inner opening along the bore to an outer opening along the root of the helical portion.
In yet another respect, a firearm suppressor including a cylindrical wall defining a central bore extending about a longitudinal axis, and one or more cooling bores spaced from the central bore, the cooling bores extending into the wall offset from the central longitudinal axis.

Abstract: A muzzle device for a firearm may include an additively manufactured body having a first end, a second end opposite the first end, and a central bore extending from the first end to the second end. The body may include a lattice of triply periodic minimal surfaces that define an interconnected network of channels extending through the body such that gases produced by the firearm may flow in a random pattern from the central bore through the interconnected network of channels to cool the gases.

Abstract: A wipe-cutting tool integrated into a firearm or firearm accessory, or component thereof, which can be replaced in the field. The muzzle accessories may include a suppressor, a brake, a compensator or a flash suppressor. The components may include an endcap, the end of an accessory, a muzzle or a baffle. Cutting blades are integrated into the firearm or muzzle accessory and may be integrally formed with the suppressor or compensator tube as well as with a muzzle end cap attached to the tube. When pressed into a substrate of material suitable to form a wipe the cutting blade separates a wipe from the substrate which can be readily inserted into the suppressor or compensator at the muzzle end.

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 coaxially aligned with 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 has an inner surface separated from and confronting the outer surface of the baffle stack. An outer chamber is defined between the inner surface of the outer housing and the outer surface of the baffle stack. Flow-directing structures are in the outer chamber. An end cap is connected to a distal end of the outer housing and defines a central opening aligned with the central axis.
