An ammunition ( 3 ) can be guided out of a loading space particularly quickly and reliably by means of the ammunition feed ( 1 ), in that a pawl ( 4 ) is arranged movably on an end of the rammer ( 2 ) facing the cartridge, the pawl ( 4 ) being positionable in an engagement position ( 5 ) in order to guide the ammunition ( 3 ) out of the loading space into the magazine, the pawl ( 4 ) being arranged in a recess ( 6 ) of the ammunition ( 3 ) in the engagement position ( 5 ), the ammunition feed ( 1 ) being designed as an automatic ammunition feed ( 1 ), a control device being provided, the control device being connected in terms of control technology to at least one actuator of the rammer ( 2 ) and at least one actuator of the pawl ( 4 ), a type of ammunition being automatically selected on the basis of data of automatic target detection and/or automatic target recognition, by means of which a high probability of hitting and destruction of a target to be combated can be achieved.

US12379173 - Bullet casing impact reducer

A bullet casing impact reducer is disclosed herein. The bullet casing impact reducer includes an upper frame member and a flexible drape member configured to be hung from the upper frame member so as to extend downwardly from the upper frame member, the flexible drape member configured to absorb an impact of a bullet casing after the bullet casing is expelled from a firearm so as to reduce a likelihood that the bullet casing is deflected back towards a shooter of the firearm. In some embodiments, the bullet casing impact reducer further includes a lower frame member configured to be mounted at a bottom end of the flexible drape member, and the lower frame member and a looped lower end portion of the flexible drape member configured to collectively form a collection bin for receiving bullet casings after the bullet casings are expelled from the firearm.

US12379174 - Firearm

A compact rifle-caliber firearm is provided herein comprising a receiver body, a barrel, and a grip. The barrel is coupled to the receiver body and extends in a forward direction relative to the receiver body. The barrel includes a bore and a bore axis. The grip is coupled to the receiver body and positioned rearward relative to the barrel. The grip is operable to accept a magazine sized for rifle cartridges. The grip includes a grip depth that is less than or equal to two inches. The compact rifle-caliber firearm may further include a magazine operable to be inserted into the grip and operable to receive rifle cartridges. An interior magazine depth may be less than a length of the rifle cartridges. Rifle cartridges positioned in the magazine may be angled relative to an uppermost cartridge.

US12379175 - High-capacity automatic magazine reloader

A high-capacity magazine reloader is disclosed, including a housing having an interior defined by a left side, a right side, a top, a bottom, a front and a back. The interior retains a plurality of rounds within a spiral channel having a first end nearmost a central axis and a second end forming an opening to permit the egress of the plurality of rounds. A spiral spring is biased to provide a rotational force to a first vertical member. A second vertical member is connected to the first vertical member via a horizontal member. The second vertical member is at least partially within the spiral channel to contact the plurality of rounds and force the plurality of rounds from the first end to the opening. A magazine receiver is positioned at the opening, the magazine receiver to releasably connect to a magazine of a firearm.

US12379176 - Remotely activated firearm accessory

The invention relates to an electronic device that is used to block the accessibility of a firearms Trigger. Wherein an electronic device is mounted on a rail or rail accessory and is locked in place using a lock and frame allowing the device to fit an array of firearms. The lock and frame are in place to stop easy removal unless the possessor has the key to remove them. The device its self uses a battery to operate and picks up or sends a broadcasted transmission within a programmed range by the use of a printed circuit board (PCB) capable of receiving or sending a broadcasted transmission. Once the transmission has been picked up or sent and received it activates the electronic devices locking mechanism in the form of a electromechanical mechanism causing it to shift and allows a slide placed in front of the trigger acting as a second trigger to move back and forth allowing the movement of the firearms trigger. The slide is moved back into its original position by the use of a spring driven mechanism. When the worn device or the electronic device is out of the programmed range, the electromechanical mechanism returns to its locked state stopping access to the trigger. Making the trigger locking device a beneficial reusable safety device.

US12379177 - Captive mainspring and integral beavertail

A firearm with a mainspring assembly and a beavertail element integral to the frame. The firearm may include a mainspring assembly coupled to a lower portion of the frame, a hammer strut extending between the hammer and the mainspring assembly.

US12379178 - Modular firearm trigger system

A trigger system having a detachable trigger shoe. The trigger shoe is made detachable from the trigger bow while the trigger bow remains in an installed state within the pistol. A selectable detachment feature is provided for the connection between the trigger shoe and the trigger bow. The user can activate this detachment feature and remove the shoe while leaving the trigger bow in place. The user can then install a different trigger shoe while the trigger bow remains in place.

US12379179 - Firearm muzzle accessory

An accessorized firearm can include a firearm including a barrel having a main firing tube, the barrel provided with an alignment key; and a muzzle accessory including an accessory body having a through-channel and a surface provided with an alignment groove, the through-channel receiving the barrel of the firearm, the alignment groove receiving the alignment key, the alignment key rotationally fixing the muzzle accessory relative to the barrel.

US12379180 - Crossbow with de-cocking crank mechanism having sprockets

A crossbow with a de-cocking crank mechanism having sprockets preferably includes a cranking mechanism, which utilizes a clutch sprocket and clutch assembly axial to a drive gear, and a one-way bearing axial to a bearing sprocket to cock a crossbow. The clutch assembly includes a clutch sprocket, a flywheel surface, a friction disc, and a pressure plate. The use of a one-way bearing may control the rotation of the drive unit used to wind (take-up) an elongated connecting device. Functional properties of a crank mechanism for the winding and unwinding of the elongated connecting device such as a rope, chord or the like device for pulling a secondary object from a first position to a second position are well known in the art.
