A firearm having an aim-compensation system. The firearm includes a barrel and is configured to fire a projectile. The firearm further includes a sensor disposed on the firearm that determines an orientation of the firearm. The firearm further includes a control unit that determines an intended point-of-aim of the firearm and an actual expected point-of-aim of the firearm based on the orientation of the firearm, and the control unit determines a differential of the intended point-of-aim and the actual expected point-of-aim. The firearm further includes a muzzle device arranged on the barrel which is in communication with the control unit, wherein, when the projectile is fired, the muzzle device directs a gas toward the projectile in an amount and direction based on the differential determined by the control unit so as to exert an aerodynamic force on the projectile to alter the trajectory of the projectile towards the intended point-of-aim.

A gas tube support system for a gas-actuated firearm contains an annular or bored housing for receipt of a gas tube therein, thereby securing the gas tube during operation of the firearm. At least one or more bores are drilled or formed within the annular or bored housing to provide an impingement of the gas tube as it extends through the annular or bored housing. One or more fasteners are threadedly or otherwise received within a corresponding one of one or more respective bores, thereby securing the gas tube within the annular or bored housing. A gas-actuated firearm containing the gas tube support system is also provided.

A modular firearm muzzle attachment system provides for customizing muzzle attachment characteristics by assembling selectable muzzle attachment components corresponding to desired characteristics. The system includes a plurality of internal connectors engageable together in series in a selectable order to form an internal assembly having a conduit defined by channels extending through each internal connector coupled together to form the internal assembly. Each of the internal connectors is individually structured to have associated characteristics. Each of a plurality of shrouds is couplable to a selectable one of the internal connectors of the internal assembly such that the internal assembly extends through the plurality of shrouds to define a muzzle attachment configured for coupling to a firearm.

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.

The present invention provides a novel gas impingement and recoil mitigation system for firearms that includes separate systems that reduce recoil, muzzle rise, and user fatigue and includes a system that is of variable size to match the size and caliber of firearm to which the system will attach. The system can attach to a variety of firearms through an appropriately sized standard barrel connector. As propellant gas is redirected through a ported barrel, the force of the over-pressure wave caused by the propellant blast impinges on a piston-like weight-and-spring mechanism, which thrusts forward with a force that is opposite in direction from the typical backward force that causes muzzle rise and recoil. Numerous additional aspects are disclosed.

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.
