Abstract: Launcher apparatus and methods for toy projectile blaster air compression element cylinders with elongated breech bolts for fluid communication in alignment with projectile launching barrels capable of receiving and positioning two or more rounds advanced within the barrels from breech bolts. The piston is primed and prevented from advancing once retracted with a lock and catch mechanism. An interlock and pathway prevents subprime strokes. The air compression element receives the piston for generating fluid communication to outwardly launch received projectile rounds. The breech can receive projectiles with the breech bolt of the air compression element extending into the breech to position received projectiles into barrels.

Abstract: Launcher apparatus and methods for a toy projectile blaster with a breechless projectile alignment module having a receptacle or hopper for multiple received projectile rounds, a passage at the alignment module including a barrel seal to align received projectiles for launching through a blaster barrel, and a channel into the alignment module for a compressed air source. A pre-firing area defines a junction inside the alignment module extending between the receptacle, the channel, and the barrel seal. An actuator at the housing is linked with the compressed air source for causing compressed air to expel through the channel into the alignment module and outwardly launch the received projectile rounds.

Abstract: Muzzleloader systems including a pre-packaged propellant charge with a primer and receptacle. The muzzleloader system may include a propellant containment vessel separate from the primer and the projectile and that doesn't contact with the projectile until assembly. The muzzleloader may be rear loading, with a constriction portion forward of the breech chamber. The propellant containment vessel may include a body portion having a forward opening, with a propellant charge disposed therein and a cap portion that is crimp rolled within the mouth of the vessel to seal the forward opening. The closed end of the propellant containment vessel may define a primer receptacle configured to receive the primer. The receptacle may define a depth that is less than the primer height so that, when inserted into the receptacle, the primer extends rearwardly beyond the containment vessel. The muzzleloader system may be configured to fire only specifically configured propellant containment vessels.

Abstract: An Electronic Controlled Recoil Position (ECRP) unit is muzzle-mounted on a firearm and is designed for nearly real-time correction of the firearm's recoil. This correction can maintain a shooters aim on target or else nearly remove recoil for easier control of the firearm during full or semi-automatic fire. The ECRP unit is primarily designed as a cylindrical body that attaches to the muzzle of a firearm barrel via threaded or snap-on connection. The unit features an internal bore aligned with the barrel to allow projectiles to pass through unimpeded.

Abstract: The invention relates to ammunition, in particular to the construction of composite artillery cartridge cases and can find wide application in the production of general cartridge cases with plastic main body for artillery shots with split-cartridges and unitary loading. The abovementioned cartridge case contain a metal bottom and a plastic body fixed to it, centrally in the metal bottom is made a cylindrically shaped protrusion in which a stepped hole is formed, in which a primer for artillery cartridges is mounted by means of a threaded connection, as at the metal bottom of a plastic main body is placed a mounting ring. In the metal bottom 1 at least two blind holes are formed, with a diameter equal to 0.1 to 0.25 of the diameter of the metal bottom 1 and a depth of 0.35 to 0.5 of the thickness of the bottom of the metal bottom 1, and in the bottom of the plastic main body 2 are formed at least two protruding, fixing elements 6.

Abstract: Embodiments of the disclosure relate to adjustable stocks for firearms and methods for installing an independently sprung tensioning mechanism. The adjustable stock comprises a stock body attached to a buffer tube, with a lever-operated tensioning mechanism. The mechanism includes a tensioning block with fins to grip the buffer tube, an indexing pin, and a retaining pin. When the lever is depressed, the tensioning block and indexing pin disengage, allowing longitudinal adjustment of the stock on the buffer tube. The tensioning block applies upward pressure on the tube, compensating for rotational tolerances during assembly. Both the tensioning block and indexing pin move independently when engaging with the buffer tube but move together when disengaging. The indexing pin is biased towards the buffer tube by a spring, while another spring biases the tensioning block. The lever engages the retaining pin to retract both the indexing pin and tensioning block.

Abstract: The present invention relates to an active system configured to apply an active force to a portion of a firearm designed to contact a body of the firearm's operator, to reduce the perceived recoil of the firearm. The active system includes an actuation element capable of generating an active force, and systems for powering and selectively operating the actuation element.

Abstract: A cylindrical machine gun ammunition carrier drum device with hand crank and spindle, which allows operator to regulate belt-fed ammunition at a proper cyclic rate of fire and reload linked ammunition in an efficient, accelerated manner. This retract and release belt-fed ammunition method would provide proper tension and uniformity to the linked rounds, preventing the weapon from malfunctioning and improve cyclic dispersion of ammunition. This method applies to all calibers of belt-fed personal and crew-served automatic weapons. The external hand crank and internal spindle would work in unison to recover the belt if it is yanked from the cylindrical drum container prematurely. A flexible warning device ribbon connected by ammunition links would ensure all rounds are expended from within the drum when abridged from spindle to belt. Additionally, this internal warning device can be linked between belts at operator's preference.

Abstract: The present disclosure provides systems and techniques that can be implemented in a gun, such as an electromechanical gun. The gun may charge a capacitor bank, identify a trigger break based on an output generated by a trigger sensor, and transmit a signal based on the trigger break. Transmitting the signal may result in the capacitor bank discharging electric charge such that electric current is directed at an actuator mechanism so as to cause displacement of the actuator mechanism, and the displacement of the actuator mechanism may result in the propulsion of a projectile through a barrel of the gun. The gun may determine that a projectile has been fired based on an output of an accelerometer or a gyroscope, and the gun may recharge the capacitor bank in response to determining that the projectile has been fired.
