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.

US12276001 - Process for preparation and use of inorganic markers for security identification/marking on explosives, fuses and ammunition after detonation and on firearms and metal projectiles, products obtained and process of inserting markers on explosives, fuses and ammunition and on firearms and metal projectiles

With respect to an unprecedented process of preparation of inorganic fluorescent markers under the action of infrared light, for identification and marking, by a specific insertion process, in explosives, fuses, ammunition after detonation, as well as the identification and marking of steel and metal alloys of firearms and metal projectiles an improvement includes the physical insertion of the markers in the channel and in the crucible of the pig iron production process; in this improved process, marking was carried out in the ratio of 1 part of the marker to 1,325,750 parts per mass of pig iron.

US12276072 - Tire spiker

The tire spiker is a L-shaped device deployable to a U-shaped deployed configuration having a first and second spike portion adapted to surround a tire on the front and back with a plurality of spikes held in a generally vertical disposition adjacent the tire tread. The tire spiker comprises a pair of L-shaped arms pivotally connected at one end to open to a U-shaped deployed configuration. Each of the L-shaped arms comprises a spacer and a spike portion. The spacers are hinged together. Each spike portion is on a respective spacer in a generally perpendicular disposition. Each spike portion comprises a spike side and a road side. Some of the plurality of spikes and a plurality of spike chambers are disposed in the road side of each spike portion. The spike chambers are adapted to receive a respective spike from the other spike portion in the carry configuration.

US12276183 - Perforating-gun initiator circuit

An initiator circuit for a perforating gun includes a microprocessor structured to perform a circuit-startup algorithm comprising determining whether the circuit supply voltage is stable enough for operation and, if it is, or if a predetermined period of time has passed since powering up the circuit, sending a message indicating the circuit (and thus gun) is ready for operation. The sent message may be a communication uplink indicating an address of the circuit and its ready state or a short burst of pulses indicating the circuit's ready state.

US12276371 - Gun-mounted telescoping support stand apparatus

An accessory or gun-mounted support stand apparatus including a release mechanism and locking mechanism configured to allow or prevent longitudinal movement of telescoping legs.

US12276467 - Sound, flash, and heat dissipating firearm suppressor

Embodiments described herein relate to suppressors for reducing or eliminating sound, flash, and/or heat generated by firearms while discharging projectiles. The suppressor includes a unitary structure containing a cone shaped nozzle disposed at one end of a body. The body has a plurality of baffles surrounding a central bore, a breech end opposite a faceplate, and a plurality of cooling channels spanning a length of the body. Each cooling channel has a first opening at the breech end and a second opening at the faceplate. The unitary structure further contains an outer ring spanning from the breech end to at least the faceplate, a longitudinal wall spanning from the breech end to the faceplate, and a plurality of radially oriented walls extending between the longitudinal wall and the outer ring. The plurality of cooling channels is disposed between the longitudinal wall, the outer ring, and the radially oriented walls.

US12276468 - Firearm sound suppressor

A firearm accessory may include an elongate body having an end that is positioned adjacent to a firing end of a barrel of a firearm. The firearm accessory may also include a piston assembly that is located at least partially within the elongate body. A first end of the piston assembly may be configured to be secured to the barrel of the firearm. The piston assembly may also include an indexing ring positioned at a second end of the piston assembly. The elongate body and the piston assembly may be rotatable relative to one another about a longitudinal axis that extends from the first end of the piston assembly to the second end of the piston assembly. The firearm accessory may also include an orientation assembly that includes a pawl and a selector component for selectively disengaging the pawl with the indexing ring of the piston assembly.
