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.

A detent mechanism is secured to the second component and includes a detent pin. A locking pin is configured to insert through the first opening and the second opening to secure the first component to the second component. The locking pin defines a detent opening positioned to receive the detent pin when the locking pin is inserted through the second opening. A release pin is positioned within the locking pin and is configured to urge the detent pin outwardly relative to the locking pin when the release pin is translated relative to the locking pin.

Abstract: A trigger device is disclosed. The trigger device comprises a housing, a trigger, a reverser, and a first pull weight adjustment mechanism. The trigger is rotatably mounted in the housing via a trigger pivot pin. The trigger comprises a trigger tooth. The reverser is rotatably mounted in the housing via a reverser pivot pin. The reverser comprises a reverser tooth. The first pull weight adjustment mechanism is coupled between the trigger and the reverser to bias the trigger in a first direction and the reverser in an opposite direction. Actuation of the trigger causes the trigger to rotate in the opposite direction, the trigger tooth to engage the reverser tooth, and the reverser to rotate in the first direction.

Abstract: An optical Boresight alignment device that leverages creation of an opto-mechanical reference to the rifle barrel so that the riflescope can be used to directly measure the axis of the rifle barrel and thereby offer the necessary feedback to precisely boresight the riflescope. An illumination multiplexer module (IMM) allows the riflescope to function as an illuminated precision autocollimator with which to optically measure the barrel angle. The present invention leverages the two most accurate rifle components: the barrel and the riflescope themselves to directly measure the axes of each device, the optical (riflescope) and the mechanical (barrel). This is an improvement over existing methods by successfully using the external surface of the rifle barrel as a kinematic mechanical reference.

Abstract: A rifle has a fixed main body, including a barrel, a receiver with an upper opening, and a breech element. A trigger group is at least partially housed in the receiver, including a trigger and a hammer device operable by the trigger. A carriage assembly includes an assembly body and a shutter group at least partially housed in the assembly body. The carriage assembly is positioned on the receiver at the upper opening and is axially movable by a user between an advanced shooting configuration and a retracted rearming configuration. Upon axial movement of the carriage assembly, between the retracted and advanced configurations, the shutter group is first moved axially in translation and then in roto-translation. The shutter group includes a central body and a command pin protruding radially from the shutter body. The command pin engages the assembly body so reciprocal interaction guides the shutter group in rotation.

The cover structure with a double cover structure includes: a shooting case main body having an inner space with an open upper side; a cover member seated on the open upper side of the shooting case main body to seal the open upper side; and a cover fixing member coupled to the shooting case main body to fix a position of the cover member, so that the position of the cover member is strongly fixed while simplifying a structure by the double cover structure to increase an internal pressure of the shooting case, thereby increasing a range of munition and maintaining performance of munition.

Abstract: An accessory slide stop is retrofit for commercially available and military application pistols. The slide stop acts as an add-on lever that replaces an existing lever of the pistol. The slide stop helps decrease the time it takes to reload the pistol. The slide stop is an extended body over that which is known in the art. The slide stop optimizes a position from which the slide stop can be hit by the operator, allows the operator to use either hand as the his or her support hand (non-trigger hand) without having to include two slide stops on each side of the pistol, and even changes the direction in which the operator is allowed to hit the slide stop in order to release the slide such that it is consistent with the direction in which the operator's support hand is already traveling as a result of reloading a charged magazine into the pistol.
