Abstract: Systems for universally locking a trigger of a firearm are provided that require authentication to transition the firearm to an unlocked state. In general, examples of the systems for universally locking a trigger of a firearm described herein are located in an interchangeable grip portion of the firearm or mounted to an accessory rail of the firearm. Embodiments of the system generally include trigger interference or blocking members to prevent actuation of the trigger until the authentication system has authorized the user to fire the firearm. Once the system is authenticated, embodiments of the system remain in an unlocked state while the user is grasping the firearm. When the user removes their hand from the firearm, embodiments of the trigger locking system automatically returns to a locked state, reducing or eliminating unauthorized use of the firearm.

Abstract: A method and apparatus for producing gun barrels having a grooved or ribbed inner surface with straight or helical grooves or ribs, by providing a metallic hollow cylindrical pre-form, placing the pre-form on a core mandrel being part of a flow forming machine having a main machine axis, the core mandrel having a structured outer surface comprising ribs and/or grooves extending straightly parallel to and/or helically around the main axis; and applying forming rollers, in a roller arrangement, to the outside surface of the pre-form so as to apply radial pressure on the pre-form such that its material begins to flow. As the rollers apply force upon the pre-form, a relative motion between the pre-form and the rollers is performed by moving the pre-form in axially parallel to the main axis through the roller arrangement or by moving the roller arrangement alongside the pre-form.

Abstract: A firearm stock with barrel-centering feature has an elongated body defining an elongated receiver channel and an elongated barrel channel, the receiver channel defined in part by a flat floor surface facing in upward direction, the receiver channel defined in part by opposed sidewalls extending above the floor surface, a fastener facility at the rear of the receiver channel operable to connect to the tang of the receiver, and a lateral adjustment facility forward of the fastener facility and operable to secure the receiver in a selected lateral angle of pivot about the fastener facility, such that the barrel is centerable within the barrel channel to avoid the barrel touching the stock. The lateral adjustment facility may include a set screw having an axis parallel to the floor surface of the stock. A pair of set screws opposing each other may secure the action in a selected lateral position.

Abstract: A method of sealing and securing of a shaped charge comprising a casing having a detonator, an explosive filler disposed within the casing having a cavity formed therein, and a liner disposed over the explosive filler. The method includes coating at least one portion of the shaped charge with a curable sealant, and exposing the curable sealant to radiation to cure the curable sealant. The radiation may be in the ultraviolet range and have a wavelength in a range of from about 200 to about 400 nanometers. In addition, the at least one portion of the shaped charge that is coated with the curable sealant may be a surface of the liner, a joint between the liner and the casing, over the detonator, or any combination thereof. The liner may comprise a metallic liner.

Abstract: An advanced gas piston operating system for Armalite Rifle (AR) and Armalite Rifle variants. The advanced gas piston system may include a barrel having a gas port formed through the barrel wall, a gas block assembly, a gas piston assembly, and upper receiver assembly, a sending block, rack and gear assembly, and a bolt carrier assembly with an attached rack. In such a system, a portion of the combustion gases from a fired projectile travel through a gas port in the barrel into a gas block assembly which drives a piston forward which compresses a main spring on an attached rod. The opposite end of the rod is attached to a sending block rack and gear assembly with the gear rotatably engaged with the teeth of another rack that is attached to the bolt carrier assembly. As the gas piston assembly moves forward, the bolt carrier assembly moves rearward until the main spring is fully compressed. Decompression of the main spring returns bolt carrier assembly forward loading the next round into the chamber.

Abstract: A pistol with a magazine angle swept backward in relation to the barrel increases the barrel length for a given pistol length without deviating from the grip ergonomics of conventional modern pistols. By angling the magazine in this manner, the muzzle velocity of a pistol may be increased for a given pistol length. Alternatively, the pistol length may be minimized for a given muzzle velocity.

Abstract: A mount assembly for securing accessories to an underlying firearm assembly. The mount assembly includes a base that is constructed to be secured to an underlying firearm and an accessory support that is moveable relative to the base. An interface arrangement is provided between the base and the accessory support such that the accessory support can be rotated relative to the base between a first orientation that is laterally inboard of the base and a second orientation that is laterally outboard of the base to accommodate break-action operation of an underlying firearm when the accessory mount assembly is secured to the firearm.

Abstract: Various examples of a modular trigger control unit for firearms are described. The trigger control unit can be removably installed on a grip frame and installed between the grip frame and a slide assembly of a semi-automatic firearm. The trigger control unit includes at least a trigger pin and a trigger pivotable around the trigger pin when pulled. In response to the trigger being pulled by a user when the trigger control unit is installed between the grip frame and the slide assembly, a firing pin lug of a striker-firing mechanism in the slide assembly is released thereby allowing a striker of the striker-firing mechanism to move forward with respect to the slide assembly. Moreover, the trigger control unit is secured to the grip frame at least by the trigger pin such that removal of the trigger control unit from the grip frame requires removal of the trigger pin.

Abstract: The inventive disclosures pertain to an improved handgun (and related retrofit/after-market kits) that incorporates an improved gunsight and ergonomically enhanced pistol-grip member. In embodiments, an elongated gunsight-augmentation member is adapted to be inserted between a handgun's existing rear and front gunsights such that the gunsight has been basically transformed into a barrel-length U-shaped channel that makes it clear to a user how to line-up a target, while ensuring that the entire length of the device has a smooth shape and edges to significantly reduce snagging when drawing the firearm. The gunsight-augmentation member can also incorporate an internal fiber-optic rod as a visual aid to line-up a firearm. In variations, the improved handgun incorporates an ergonomically enhanced finger-receiving member disposed at the bottom surface of the pistol-grip and/or magazine that is especially useful for compact handgun designs.
