Patent number: 11448482Abstract: A firearm light accessory with one or more embodiments enabling its user to control brightness of the colored beam or white beam of the firearm light. It comprises three items: a see-through lens cover with its base (18) attached to its cap (10) by a spring-assisted hinge, iris (12), and transparent colored disk (20). The cap is closed for the colored beam and opened for the white beam. Iris adjusting lever (14) protrudes through lens cover base (18). The lever position determines the amount of light passing through the accessory, so as to control brightness. The accessory can be produced with minimal equipment and materials by a person having ordinary skill in the art. Costs of production compared to the prices of colored filter devices not having brightness-control ability indicate commercial feasibility. Benefits include reducing glare, preserving the user's night vision, and reducing the user's risk of detection, thereby to assist hunters and to protect persons in combat or similar danger.Type: GrantFiled: May 15, 2019Date of Patent: September 20, 2022Inventor: Gary Keith Robb

Patent number: 11428485Abstract: A firearm for firing case-telescoped (CT) rounds includes a barrel configured for transit of a bullet of a live CT cartridge in a live-fire operating mode. The live CT cartridge is chambered and fired from a live-fire chamber installed in the live-fire operating mode. The firearm further includes a blank-fire chamber configured to chamber and fire a blank CT cartridge in a blank-fire operating mode, wherein the blank-fire chamber has a second diameter less than a first diameter of the live-fire chamber, to prevent chambering of the live CT cartridge in the blank-fire operating mode. The arrangement can enhance safety by preventing accidental firing of a live round during operation when it is assumed that only blanks are being fired.Type: GrantFiled: January 15, 2021Date of Patent: August 30, 2022Assignee: Textron Systems CorporationInventors: William Henry Engel, IV, David Timothy Horst

Patent number: 11415382Abstract: A firearm reliability system may include a charging handle insert and a variable bolt weight assembly. Other components of a firearm reliability system may include, but are not limited to, a buffer pressure plug, extractor springs, firing pin springs, one or more firing pins, and bolt buffers. The firearm reliability system may address weaknesses in the common rimfire AR bolt system. Using the firearm reliability system, malfunctions may be essentially eliminated. Each component of the firearm reliability system plays a part and interfaces with the others (i.e., the bolt weight spreads the impact on the buffer into a larger area, while reducing the speed at which the bolt impacts the backplate, which then reduces the energy transferred to the buffer pressure plug and thus the impact with the lower receiver).Type: GrantFiled: October 16, 2020Date of Patent: August 16, 2022Inventor: William MacNeill

Patent number: 11408713Abstract: An entangling projectile for use with a projectile deployment system includes a pair of pellets. At least one of the pair of pellets has a head with a head outer diameter and a shank with a shank outer diameter, the shank outer diameter being less than the head outer diameter. A tether connects the pair of pellets. A centering shroud is carried by a shank of the at least one of the pair of pellets. The centering shroud has at least one tether opening formed therein to receive the tether. The tether is coupled to the pellet and extends along the shank of the pellet and through the at least one tether opening formed in the centering shroud.Type: GrantFiled: June 24, 2021Date of Patent: August 9, 2022Assignee: Wrap Technologies, Inc.Inventor: Elwood Norris

Patent number: 11402188Abstract: A two piece aerodynamic pusher consisting of a body and tailpiece. This pusher fits into a standard 40 mm cartridge case by means of three sabots. After the cartridge case is functioned, the combustion gases push the projectile forward and ignite a delay column located in the rear of the pusher. Upon muzzle exit, the sabots discard and the pusher continues down range as the delay column burns. Once the delay has burned, a charge located in the pusher body is ignited, pushing the payload out of the front of the projectile. The cap pops off, and the pellets are dispersed. This effectively moves the payload release point from the muzzle until a designated point down range based on the delay length.Type: GrantFiled: August 20, 2021Date of Patent: August 2, 2022Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: David Chalfant Manley, Sean Mulvihill

Patent number: 11397072Abstract: A piston/rocket projectile for use within a launcher system having a barrel and method of firing such are presented herein. The projectile comprises a projectile body having a combustion chamber for propellant, a piston moveable to extend out a base of the projectile as a result of ignition of propellant in the combustion chamber, and vents for expulsion of combustion products from the ignition of propellant out of the projectile base after initial movement of the piston. A casing is secured to the base of the projectile body, enclosing the piston and vents prior to the ignition of propellant, and a frangible joint is disposed between the casing and the base of the projectile body. Upon ignition of propellant in the combustion chamber, the projectile piston is forced against the casing and causes the frangible joint to break, leaving the casing in the barrel.Type: GrantFiled: May 26, 2021Date of Patent: July 26, 2022Inventor: Vincent Battaglia
