A muzzle brake compensator has a mount configured to connect to the barrel in registration with the barrel axis, a body defining an interior chamber and connected to the mount, the body defining a bullet aperture registered with the barrel axis, an exhaust port apart from the bullet aperture, a nozzle element connected to the exhaust port and rotatable about a port axis, and the nozzle element defining an exhaust aperture having an exhaust feature having a characteristic angularly offset from the port axis, such that the rotational position of the nozzle element determines a direction of an exhaust force with respect to the port axis. The nozzle element may protrude laterally at an angle from the barrel axis. The nozzle element may be lateral to the bullet aperture. A pair of exhaust ports may be located on laterally opposed positions with respect to the bullet aperture.

A muzzle booster or similar device for regulating firearm discharge gases from an autoloading firearm is disclosed. The muzzle booster may include a shroud and an interior component. The interior component may include a blast baffle that is configured and dimensioned to provide internal and external geometries such that exhaust pressure within the gas system is extended as a function of time to increase the overall minimum pressure impulse from the gas system into the operating mechanism of the host firearm. The blast baffle or interior component may be of M baffle type, K baffle type, or other baffle design, including monocore designs, or baffle designs integrated into monocore designs. The shroud and the interior component may cooperate with the barrel of the host firearm to form a taper lock system for securing the muzzle booster or device to the host firearm barrel.

A plug for insertion into a blast-tube exit cavity of a gun-blast diffuser comprises a plug front surface, a plug rear surface, a plug side surface that extends between the plug front surface and the plug rear surface, a body, comprising a polyurethane foam, and a substrate, coupled to the body and comprising a conductive nonwoven fabric, impregnated with a polyurethane matrix. The plug front surface of the plug is formed by the substrate. The plug rear surface of the plug is formed by the body. The plug side surface of the plug is formed by the substrate and the body.

A Universal Custom Recoil Solution will comprise of, a provided Firearm or barrel, prismatic shaped shell housing mounted or connected to the Gas Block Base, a Gas Block Base with pathways to direct firearms gas pressure from firing bullet into device interior pushing a Counter Weight, and Spring to counter act the firearms recoil when fired. This device is fitted to or around a provided barrel where the Counter Weight and spring are mounted on and reciprocate from front to back of the systems interior volume. The systems main function is to create a counter balance to the firearms kinetic energy by providing a moving mass, to counter the recoil from the firearms action movement when firing. The gas pressure is also expelled and redirected allowing the device to cycle synergistically with the firearm actions.

A muzzle brake has body having a muzzle end and an exit end with at least one side connecting the ends. A muzzle aperture in the muzzle end is sized and configured to fit a firearm muzzle. A projectile aperture in the exit end extends to the muzzle aperture. A line segment within the space of the muzzle aperture aligns with the centerline of the firearm and defines a projectile line through the body. Apertures pass through the body with their generating lines being perpendicular to the projectile line. The apertures are shaped to allow more gases to escape in one direction and to contain gases in the opposing direction. This causes the gases to exert forces on the muzzle brake which compensates for the tendency of the muzzle to rise when the firearm is fired.

A muzzle brake for a firearm having an outer body with a sidewall that defines at least one aperture and an inner tube that fits inside the outer body. The inner tube includes at least one aperture that corresponds to the at least one aperture of the outer body. The inner tube is rotatably mounted to the outer body. The muzzle brake may adopt an open position in which the apertures of the outer body are in communication with the apertures of the inner tube and a closed position in which the apertures of the outer body are not in communication with the apertures of the inner tube. When in the closed position, propellant and projectiles may be easily loaded into the barrel and when in the open position, gases and heat may easily escape, which minimizes or counteracts recoil.
