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.

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.
