An aiming method for a weapon system including a weapon secured to a chassis, as well as an aiming device implementing such a method. The weapon system includes a computer having in an internal memory a nominal firing profile defined by the extreme elevation and relative bearing aiming instructions that are possible for the weapon, in the reference frame associated with the chassis, when the latter is in a firing position on a horizontal ground. The boundaries of the nominal firing profile are converted so as to determine a transformed firing profile which is delimited by the extreme directions of fire that are possible in the reference frame of the chassis when the latter is in the firing position on the field, and finally the operating firing profile is determined for the aiming, which is defined as the geometric intersection of the nominal firing profile and the transformed firing profile.

A direct fire weapon system training and firing aid comprising a shoulder bar attachment for elevating and/or traversing a direct fire weapon system is disclosed. It may have an elongate arm for attachment to the weapon system and extending in a generally rearward direction from the weapon system. Once coupled to a weapon system, it gives a user a stable method of supporting and moving the weapon system, allowing the user to quickly elevate and traverse the weapon system by giving the user an additional point of contact, for example at the shoulder or under the arm, to support and stabilize the weapon system.

An electric winch provides motive force, allowing the cannon to be pulled out of battery and returned to battery in a safe and controlled manner. After the system is attached to the large caliber weapon system, the operator can stand a safe distance away and control the complete operation with a remote. The recoil exerciser can be quickly attached to any large caliber weapon system via hooks and a wear-resistant sling.

An automated weapons system is comprised of a plurality of weapon subsystems each comprising at least one human transported weapon subsystem. Each of the plurality of weapon subsystems is comprises a barrel, a targeting subsystem, a computational subsystem, positioning means, and a firing subsystem. The barrel is utilized for propelling a munition from each of the plurality of weapon subsystems aimed towards an area of sighting. The targeting subsystem identifies a chosen target for each of said plurality of weapon subsystems in the area of sighting. The computational subsystem, responsive to the targeting subsystem, determines where the chosen target is for each weapon subsystem (out of plurality) and where the respective barrel needs to be aimed for each weapon subsystem (out of plurality) so that the munitions will strike the chosen target. The positioning means adjusts the aim of the munitions for each weapon subsystem, responsive to the computational subsystem, out of plurality of weapons subsystems. The firing subsystem, fires the munitions from at least one to each of said plurality of weapon subsystems at the chosen target for one of the weapons subsystems, responsive to the positioning means from at least one of the plurality of the weapons subsystems.

A rifle bipod with a rifle support for operatively receiving and supporting a portion of a rifle, as well as two legs each having a tubular upper and lower portion and telescopically arranged with an urging element urging the portions and into an extended position is disclosed with a cam lock arrangement allowing infinite length adjustability between the telescoping upper and lower portions. Each leg has a foot attachment to releasably receive interchangeable feet whereby each leg is operatively able to engage a surface. Bipod also includes a stabilising arrangement pivotably attaching the legs to the rifle support at a commensurate off-vertical angle with a biasing element to operatively bias both legs towards each other. The stabilising arrangement includes a linkage to maintain the off-vertical angle commensurate as the legs pivot apart, wherein the rifle support is height adjustable via the telescoping legs and the linkage maintaining the off-vertical angle.

A method of assembling a lower receiver and an upper receiver of a firearm is disclosed. The method comprising steps of providing a threaded fastener; inserting the threaded fastener into a ratchet handle; mounting a ratchet gear into the ratchet handle, wherein the threaded fastener passes through an aperture of the ratchet handle and threads into the ratchet gear; positioning a locking plate at the lower receiver, wherein the locking plate is fixed to the ratchet handle by turning and tightening the ratchet handle with the engaged ratchet gear for locking to the locking plate in a locked position; and on the opposite side of the lower receiver, inserting a threaded pivot pin into an aperture of the locking plate from the opposite side of the lower receiver, wherein a threaded rod of the ratchet gear is threaded into a threading cavity of the pivot pin.

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 mounting system configured for coupling a device to a vehicle and providing for movement and remote operation of the device includes a first member for removably coupling the device to the mounting system, a second member rotatably coupled to the first member, a rotational actuator configured to rotate the first member relative to the second member about a first axis, a linear actuator configured to move the first and second members together, a device actuator configured to operate the device, and a deployment apparatus configured to move the device from a stored position to a deployed position.
