Abstract: 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.

Abstract: A device for reducing a recoil force generated by firing of a firearm. The device comprises elongated chamber in the form of an outer cylinder concealed in the forend of a long firearm and having a communicating port with the barrel of the gun situated a short distance beyond the tip of the bullet. The outer cylinder comprising a lead filled cylinder sliding freely back and forth into the elongated chamber. Upon firing the gun, a portion of the explosion gases will penetrate through the communicating Port into the recoil reducing cylinder and forcefully push the lead field cylinder forward against the distal bumper therefore pulling the gun forward and dampening the recoil force. After firing a spring situated distal to the lead cylinder pushes the cylinder backward to its initial position.

The barrel is movably mounted within a stock for propelling a projectile towards an area of sighting. The targeting subsystem identifies a chosen target in the area of sighting and locking onto the chosen target at a first time.

The positioning means, adjusts the position of the barrel within the stock, responsive to the computational subsystem. The firing subsystem, activates firing at the firing time to propel the projectile through the barrel at the chosen target at the firing time.

Abstract: A firearm locking system that can lock a trigger by remote activation by an authorized user using a trigger lock that can block a trigger of a firearm from being pulled sufficiently to fire the firearm, The trigger lock can be advanced forward into the locked configuration and retracted into an unlocked configuration with the use of an actuator, such as a motor, Tamper-resistant features can be employed to prevent unauthorized users from disabling the firearm locking system. For example, when the trigger lock blocks the trigger, the trigger lock can also lock the upper receiver from being removed preventing access to the firearm locking system from the top of the firearm. The actuator or can be detachably connected to the trigger lock such that when the grip is removed, the actuator disconnects from the trigger lock causing the trigger lock to enter a jammed configuration.
