A suppressor baffle and a suppressor for a firearm. The suppressor includes a firearm attachment portion, a sleeve portion, and a baffle assembly with a plurality of baffles. At least one of the baffles includes a tubular body with a proximal exterior surface. The proximal exterior surface has a plurality of spaced-apart annular ridges. A first annular ridge includes a first annular compression surface and a first annular expansion surface, and a second annular ridge includes a second annular compression surface. The ridges are shaped and arranged to define a convex first expansion corner between the first annular compression surface and the first annular expansion surface, and a concave first compression corner between the first annular expansion surface and the second annular compression surface. Gas flowing along the proximal exterior surface expands at the first expansion corner and compresses at the first compression corner to dissipate energy in the gas.

Expansion-compression baffle

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 at a distal end of the dissipation structure. The sleeve defines an internal volume that at least partially receives the dissipation structure. The end cap assembly and the dissipation structure at least partially define one or more distal chambers communicating with the internal volume. The end cap assembly defines a first, a second, and a third passage, each communicating with an exterior of the accessory. The first passage allows a bullet to pass through. The second passage includes a port in the end cap assembly radially outward of the first passage. The third passage includes a port located radially outward from the port of the second passage.

End cap muzzle control

A suppressor baffle and a firearm suppressor for suppressing the volume of the report of a firearm includes a fitting for mounting the suppressor on a firearm, a sleeve, and a baffle assembly. The sleeve is supported by the fitting. The baffle assembly is at least partially received in an internal volume defined by the sleeve. A first baffle in the plurality of baffles has a conical section with a proximal opening and a port. The port is elongate in a direction along the circumference of the conical section. The port provides a fluid path through the conical section from an entrance chamber of the suppressor to an internal conical volume defined by the conical section. Gas flowing along the first baffle is directed through the port, causing energy dissipation in the gas.

Evacuating entrance chamber via blast baffle

A firearm suppressor for use with a firearm includes a sleeve, an end cap, a baffle, a first exhaust passage, and a second exhaust passage. The sleeve has an inlet end, an outlet end, an interior volume, and an interior surface. The baffle is received in the sleeve and has an annular body with a central passage through the annular body. The first exhaust passage extends along a longitudinal axis of the sleeve and through the central passage of the baffle and allows gas to exit to the exterior of the sleeve. The second exhaust passage has a plurality of distinct exhaust gas channels. The distinct exhaust gas channels provide separate flow paths for exhaust gas to exit to the exterior of the sleeve.
