Abstract

A suppressor mount device can include a first end having a barrel coupling feature adapted to couple the suppressor mount device to the barrel of a firearm. The device can further include a second end oriented opposite the first end along a bore axis and a suppressor coupling feature adapted to receive and retain a firearm suppressor. The device can further include a bore forming a void along the bore axis within the suppressor mount device, the bore adapted to allow passage of a projectile along the bore axis from the first end to the second end. The device can further include a reaming feature formed on an outer surface of the second end adapted to engage an inner surface of the firearm suppressor. The reaming feature can include a channel which is at least partially oriented non-parallel and non-perpendicular to the bore axis.

Abstract

An energy capture and control device can include a central chamber oriented along a central axis within an outer shell. The central chamber can have an inlet configured to receive a bullet from a firearm muzzle, and a central chamber outlet along the central axis. The device can also include an off axis chamber oriented within the outer shell in fluid communication with the central chamber and a fluid outlet to allow fluid to escape from the off axis chamber.

Abstract

A firearm accessory system that self-tightens in response to firing comprises an interface structure (e.g., flash hider mount) threadably coupleable to a muzzle end of the firearm, and a suppressor threadably coupleable to the interface structure at a proximal end of the suppressor. At least one of the interface structure or the suppressor can comprise a plurality of discharge gas deflector openings formed at an angle relative to a central axis, and that exhaust discharge gases out through a distal end of the suppressor. In response to firing a projectile through the interface structure and the suppressor, discharge gases flowing through the plurality of discharge gas deflector openings cause a torsional force to tighten the respective one of the interface structure or the suppressor to the respective one of the muzzle end or the interface structure.

Abstract

A firearm flash hider can include a base module and at least one vented flash control module. The base module can have a longitudinal boreline which is fluidly coupleable to a muzzle end of a firearm to allow a projectile to pass therethrough. The base module can also have an inlet port which is operable to receive at least a portion of a flash generated by firing the projectile. The vented flash control module can be arranged along the longitudinal boreline distal to the muzzle end. The vented flash control module can also have a flash chamber bounded by at least one wall that at least partially defines a geometry of the flash chamber and extends both radially and longitudinally from the boreline and translates circumferentially as it extends longitudinally. The flash chamber terminates at a circumferential angle of rotation from the inlet port where the circumferential angle of rotation being less than 180 degrees. The flash hider can typically have from one to four vented flash control modules oriented in series.

Abstract

A thermal mirage reducing device for firearms is disclosed and described. The thermal mirage reducing device includes a heat control shell oriented along a horizontal longitudinal axis corresponding to a bore line of a firearm. A cross-sectional profile of the heat control shell taken perpendicular to the longitudinal axis is asymmetrical about a vertical plane dividing the heat control shell along the longitudinal axis. The cross-sectional profile has a heat-directing portion protruding on one side of the vertical plane. The heat-directing portion extends to a high point that is vertically higher than any other point in the cross-sectional profile and laterally offset from the vertical plane. The cross-sectional profile does not intersect the line of sight of the firearm.

Abstract

A firearm discharge gas flow control module is fluidly coupleable to a muzzle end of a firearm to allow a projectile to pass therethrough. The gas flow control module includes an inlet port, operable to receive at least a portion of a discharge gas generated by firing the projectile, and a gas chamber, bounded by at least one wall that at least partially defines a geometry of the gas chamber. The gas chamber extends both radially and longitudinally from the inlet port and translates circumferentially as the gas chamber extends longitudinally. The gas chamber terminates at a circumferential angle of rotation from the inlet port, the circumferential angle of rotation being less than 180 degrees.

Abstract

A particulate capture module for a high energy discharge device includes a particulate capture shell having an inlet and an outlet. The shell inlet can receive a high energy material discharged from the high energy discharge device. The particulate capture module can further include a self-healing particulate capture material arranged within the particulate capture shell to enable the high energy material to pass through the self-healing particulate capture material. The self-healing particulate capture material can capture particulates associated with discharge of the high energy material from the high energy discharge device.

Abstract

A firearm discharge gas flow control device can comprise a first gas chamber fluidly connectable to a muzzle end of a firearm to allow a projectile to pass through and to receive a first portion of a discharge gas generated by firing the projectile. The device can also comprise a second gas chamber fluidly isolated from the first gas chamber and fluidly connectable to the muzzle end of the firearm to receive a second portion of the discharge gas, the second gas chamber having a flow control barrier to modify a flow of the second portion of the discharge gas.

Abstract

An interchangeable, modular firearm muzzle mountable system can include a first firearm muzzle mountable device and a second firearm muzzle mountable device. Each device can have an inlet end coupling feature proximate to an inlet end of a central chamber and an outlet end coupling feature proximate to an outlet of the central chamber. The central chamber can be oriented along a central axis within an outer shell and the inlet and the outlet can be configured to allow a projectile from a firearm to pass along the central axis. The inlet end coupling feature of the first device can be removably coupleable with a muzzle end of a firearm and the inlet end coupling feature of the second device can be removably coupleable with the outlet end coupling feature of the first device beyond the muzzle end of the firearm.
