Abstract: A toy firearm includes: a hollow firearm body; a cartridge module separably coupled in front of the firearm body to store a plurality of BB bullets to be fired; a gas discharge module to supply introduced gas to the BB bullets stored in the cartridge module by sequential control using a solenoid valve; an electrical sound module electrically connected to the gas discharge module to generate an electrical high voltage sound for a predetermined time with respect to a point in time of firing the BB bullets stored in the cartridge module; and a gas tank disposed in a grip of the firearm body to temporarily store the gas and supply the stored gas to the gas discharge module, wherein the cartridge module includes a pair of barrels arranged side by side at a predetermined angle along front and rear sides.

Abstract: Police officers use conducted electrical weapons (“CEWs”) and cameras. A camera and a CEW may cooperate to improve the performance and use of the CEW and evidence collection by the camera. A camera and a CEW may also cooperate to improve the safety of the user and the target. Improvements may include improving targeting of the CEW, identifying and classifying body parts of the target as suitable or unsuitable for electrode deployment, adjusting electrode trajectory prior to launch, and automating electrode launch. Evidence collection may be improved by recording placement of electrodes on the target. Safety of the target may be improved by monitoring the movements of the target and altering characteristics of the delivered stimulus signal if potential harm to the target may occur.

The clutch is disengagable without the use of tools to allow the dial to rotate relative to the rotating member for zeroing the aiming device. The locking mechanism may include a lock release that is accessible from outside of the dial and movable relative to the dial and the rotating member to release the locking mechanism. Methods of zeroing locking adjustment knobs are also disclosed.

Abstract: A semiautomatic shotgun successfully uses the AR-10 receiver and the superior direct impingement gas system. A combination of locking lugs to maintain proper sequencing, a spring disposed inside of a gas impingement chamber, and a spring to cycle the action. Fouling is avoided using nickel-boron coated parts, permanent infusion of a dry film lubricant, and an angled gas port. A unique magazine feed lip and barrel extension feed ramp and the magazine maintaining the shells at a slight angle upward, and a bolt face having a rear facing partial bevel avoid jamming and snagging. The present invention also teaches raised gas tube and gas key to accommodate the larger bore of the shotgun. The combination achieves an AR-10 based shotgun which has the advantages of direct impingement cycling (less recoil, greater accuracy, etc) without fouling and/or jamming.

The system is characterized in that the position return component includes a line-point-plane positioning unit with balls between the two plates and a set of elastic return members connecting the two plates to one another. A corresponding device is also disclosed.

Abstract: The buttstock assembly uses a modular design including interchangeable end attachments and sling strap connectors. The interchangeable end attachments allow the buttstock to have different toe heights and configurations for different shooting applications. The interchangeable strap connectors allow the use of either quick-disconnect style sling swivels or more traditional fixed strap loops as desired. The buttstock assembly also uses a “trigger” style locking mechanism to selectively position and lock the buttstock along the length of the extension tube to adjust the overall length of pull of the weapon.
