A suppressor has a central expansion chamber and a coaxial expansion chamber. A front cap has at least one port in fluid communication with the coaxial chamber and an adjustable cover selectively movable between a closed position, in which the cover closes each port, and an open position, in which each port is open, thereby allowing selective control of the flow of gases and particulates exiting the coaxial chamber through each port.

A variety of apparatuses and associated methods are provided for providing a retractable suppressor system for gas generator systems such as a firearm. One embodiment includes a suppressor system that includes a retractable structure and housing, a fixed baffle, floating baffles, and springs to displace the floating baffles within the suppressor as the suppressor is extended from the housing along a gas generator system, e.g. a barrel of a firearm and thereby enclose the barrel within the suppressor. Embodiments of the invention permit full retraction, partial retraction/extension, or full extension of an exemplary suppressor with respect to an emission section of the gas generator e.g., firearm muzzle. Embodiments of the invention include an external latch which enables an operator to latch or unlatch the suppressor as it moves from one position to another and prevents accidental activation. Embodiments of the invention are configured to operate with accessory mounting systems.

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.

An apparatus and system are provided for a firearm suppressor. The system, in one embodiment, includes an elongated core comprising at least one series of ports extending radially from a bore to an exterior surface of the core, where the at least one series of ports is disposed linearly along a longitudinal axis of the core, and where the elongated core comprises at least one trough formed in the exterior surface of the core. The system also includes a baffle sleeve disposed around the core, the baffle sleeve having at least one uninterrupted fluid pathway extending along the exterior surface of the baffle sleeve and formed by interdigitated baffle ridges, and an outer tube disposed around the baffle sleeve.

A noise suppressor design is provided that improves reduction of muzzle blast without increasing the size or weight of the noise suppressor. In various embodiments, a noise suppressor for a firearm might comprise a central axis and a plurality of baffles that each nests within adjacent baffles along the central axis. A first baffle and a second baffle of the plurality of baffles might each comprise a proximal end having a first/second aperture oriented along the central axis and a plurality of notches in the proximal end adjacent to the first/second aperture and aligned in a first orientation. A third baffle of the plurality of baffles might comprise a proximal end having a third aperture oriented along the central axis and a single notch in the proximal end adjacent to the third aperture and aligned in a second orientation that is 90 degrees relative to the first orientation.
