US12636403 - Firearm trigger mechanism
A trigger mechanism that can be used in AR-pattern firearms has a hammer, a trigger member, a disconnector, a locking member, and a “three position” safety selector having safe, standard semi-automatic, and forced reset semi-automatic positions. In the standard semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer such that the disconnector hook catches the hammer hook, at which time a user must manually release the trigger member to free the hammer from the disconnector to permit the hammer and trigger member to pivot to the set positions so that the user can pull the trigger member to fire the firearm. In the forced reset semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer causing the trigger member to be forced to the set position, the safety selector preventing the disconnector hook from catching the hammer hook, and thereafter when the bolt carrier reaches the substantially in-battery position the user can pull the trigger member to fire the firearm without manually releasing the trigger member. The locking member is pivotable between a first position at which the locking member mechanically blocks the trigger member from moving to the released position and a second position at which the locking member does not mechanically block the trigger member allowing the trigger member to be moved to the released position. The locking member is spring biased toward the first position and moved against the spring bias to the second position by contact from the bolt carrier during forward movement of the bolt carrier as the bolt carrier reaches a substantially in-battery position.

US12624910 - Reduced weapon system blowback
A reloading firearm featuring a mechanism to reduce the blowback of toxic propellant gasses towards the warfighter. The reloading assembly acts in plural segments to increase the firing chamber-closed dwell time, while limiting adverse impact to the overall nominal rate of fire. Greater dwell time corresponds with reduced exposure of the warfighter to propellant gasses. Moreover, increasing the dwell time without otherwise altering the firing cycle has the additional effect of delaying the breech opening after the cartridge is fired. This delay in breech opening permits gas pressure at the muzzle, which may be elevated and/or constrained by flash and/or sound suppression, to dissipate before the breech is opened. Accordingly, when the breech opens later in the firing cycle, there is a reduced pressure gradient across the combination of barrel and firing chamber, which reduces a driving force of propellant gasses towards the warfighter via the open breech.

US12546547 - Firearm platform and method of connecting upper and lower receivers
A firearm platform and method of connecting an upper receiver to a lower receiver. The upper receiver has a pivot lug and a takedown lug with perimeter openings in opposite directions. The lower receiver has a locking member that pushes against the takedown lug which causes the upper receiver to displace forward. As a result of the forward displacement, a pivot pin in the lower receiver exerts an opposing force against the pivot lug. The locking member is displaced between a locked and unlocked position through a lever located on an exterior surface of the lower receiver. When the locking member is in the locked position, the lower receiver and uppers receiver form a connection that is tight and free from slop.
US12546549 - Firearm
A firearm comprises a frame; a barrel; a hand grip; a breechblock slidable along the frame; a striker slidable in the breechblock; a longitudinal elastic device for the recovery of the recoil kinetic energy for rearming the striker; and a closing block for locking the breechblock in the closing position, the closing block having a body which extends longitudinally and having a rear wall engaged with a downward protrusion integral with the barrel, a front wall engageable with the breechblock and a longitudinal recess which opens at the front wall, where the longitudinal elastic device for the recovery of kinetic energy has a longitudinal rear portion housed in the recess and a longitudinal front portion retractable towards the inside of the recess, and is longitudinally interposed between a front stop abutment solidly constrained to the breechblock and a rear stop abutment solidly constrained to the frame.
US12546550 - Firearm
A firearm, particularly a gun operating by recoil exploitation, comprising: a frame; a barrel, a hand grip; a breechblock slidable for the closing of the breech of the barrel; a striker; a longitudinal elastic device for the recovery of the recoil kinetic energy of the breechblock for rearming the striker; a release lever having a coupling position and a release position of the striker; a single action trigger mechanism comprising a trigger and a trigger transmission rod operatively connected to the trigger and to the release lever, and an antagonist lever to the release lever, the mass of the antagonist lever being distributed and arranged to strain the antagonist lever with inertial forces that contrast the release lever for preventing the accidental release of the striker.
US12546555 - Crossbow with plates supporting limbs
A crossbow includes a first plate and a second plate. The second plate is coupled to the first plate, extends substantially parallel to the first plate, and is spaced apart from the first plate. The crossbow includes an upper flexible limb coupled with the first plate at a first mounting location of the first plate and a lower flexible limb coupled with the second plate at the first mounting location of the second plate. The crossbow includes a pulley coupled with the upper flexible limb and the lower flexible limb. A draw string is operatively engaged with the pulley and is configured to move from a released position to a drawn position. A cocking mechanism is coupled with the first plate and the second plate at the respective second mounting locations. The cocking mechanism is configured to move the draw string from the released position the drawn position.
US12546557 - Crossbow crank and related method of use
A crossbow crank can comprise a drive shaft selectively coupled to a one-way bearing that allows rotation of the drive shaft and an associated spool in a first direction, and impairs rotation of the drive shaft and the spool in a second direction. The drive shaft can be automatically locked and unlocked relative to the one-way bearing, allowing the bearing to control operation of the drive shaft, via a brake. The brake can be axially compressible along the drive shaft to automatically lock the drive shaft and a sleeve so they are fixed relative to one another and rotate in unison when the drive shaft is rotated in the first direction. The brake can be deactivated by operation of a crank so that the drive shaft can rotate freely relative to the sleeve and thus the bearing in a second direction. A related method of use is provided.
US12546562 - Locking systems and methods for handguard of a firearm
A handguard is for a firearm having a firearm upper. The handguard includes a body and a cam. The body is structured to be coupled to the firearm upper. The body has a central lumen having a longitudinal axis. The cam may be coupled to the body in substantially perpendicular alignment to the longitudinal axis and is configured to rotate between an UNLOCKED position and a LOCKED position. When the cam rotates from the UNLOCKED position toward the LOCKED position, the cam rotates into the central lumen.
US12540786 - Modular AR-type safety selector with lever mounting pins
A safety selector lever assembly may include a selector core comprising an elongated section having a curved and at least one angled face, a first and second extension positioned on opposing ends of the selector core, each comprising an extension aperture, and wherein the elongated section is positioned between the first and the second extensions, a plurality of levers, each comprising: a proximal and distal end, a recess for receiving one of the first and the second extension, a pin aperture, a pin, wherein at least a portion of the pin can pass through the first pin aperture and the extension aperture, and wherein rotation of the levers to a first position enables firing of the firearm and rotation to a second position precludes firing of the firearm.
