Abstract: A reconfigurable toy gun includes a handle portion, a guide member coupled to the handle portion, and a barrel portion. The barrel portion is slidably coupled to the guide member and movable along the guide member between a first end portion of the guide member and second end portion of the guide member.

Abstract: The pistol comprises a frame (1) containing a barrel (4) slidably mounted. The pistol further comprises a firing mechanism comprising a hammer (11) mounted so that it can pivot at the rear of the pistol, and a trigger (10) secured to an actuating arm (15) that acts on means (19) of arming the hammer (11) and retaining it in the armed position. The means for arming and retaining the hammer (11) comprise a link (19) directly connected to the hammer (11) by an articulation (20) and which is actuated via a lever (40) pivot-mounted in the frame (1). The lever has a top end actuated by the barrel as the latter moves into its forward position in order to cause the lever (40) to pivot, and a bottom end acting like a cam on the link (19) by pushing it backwards in order to rearm the hammer (11).

Abstract: A magazine adapter includes a base that is structured to fit within the magazine well of a firearm, and to accept a magazine designed for smaller caliber ammunition than the original firearm. The adapter includes a bolt catch actuator slidably mounted therein. Magazines for which the adapter is intended include an upwardly extending rear projection of the follower, projecting from an opening in the rear of the magazine housing when the follower is in an upper portion of the magazine. When the upwardly extending projection pushes upward on the bolt catch actuator, the bolt catch is actuated, holding the firearms bolt in a rearward position. The magazine adapter thereby facilitates use of the original firearm controls with a caliber conversion unit, or with an upper receiver and barrel combination of a different caliber.

Abstract: A projectile launching device or launcher includes a receiver, a forestock, a trigger mechanism, and a trigger extension cable. The receiver, in one example, includes a valve, a striker, and a bolt, and is able to launch a projectile such as a paintball via pressurized gas. The loading tube is situated on the top of a barrel coupled to the receiver. The trigger guard, in one embodiment, includes a cable channel facilitating a flexible passage for the trigger extension cable. The trigger extension cable passes through the cable channel and provides a flexible linkage between the trigger and a latch wherein the latch is used to release the sear to trigger a launch.

Abstract: An improved paintball marker with electro-pneumatic firing mechanism that employs two separate solenoid valves: a low pressure solenoid valve for bolt actuation and a high pressure solenoid valve for exhaust valve actuation to fire the paintball. The exhaust valve is completely independent of the bolt movement. This eliminates the need for a mechanical ram to strike the exhaust valve. Fewer moving parts and a smaller moving mass reduces recoil and improves reliability and overall operation of the marker. Moreover, the design is more modular and allows for easier disassembly and maintenance.

Abstract: Disclosed is a system for detonating a buried explosive device by discharging an electric discharge with at least five joules of energy to detonate the buried explosive device.

Abstract: Disclosed is an inflatable article that is designed to be launched to an intended target. The article is launched by a gun in an un-inflated state and inflates upon contacting water. The target can be, for example, a person being rescued. The article is initially stored in an outer layer of material. The outer layer of material may be shrink-wrap or a foam layer. The outer layer permits the article to be retained in a compact configuration prior to being launched. This, in turn, allows the article to be launched over great distances. The outer layer is designed to rupture upon inflation of the article.

The accelerating system includes an automatic and/or automated energy adjustment mechanism and/or method, configured to allow the projectile accelerator to effectively expel a plurality of projectiles at varying energy levels and/or settings. The adjustment mechanism and/or method includes a controller configured to allow the selective selection of energy levels and/or settings falling below an upper energy level or setting.

Abstract: A cleaning apparatus for a cartridge chamber of artillery, including: a rotary member having a power supply part mounted thereinto and a motor rotated by receiving the power from the power supply part; a cleaning member having a rotary body operated cooperatively with the rotation of the motor, slant cleaning parts coupled slantly to the front portion of the outer periphery of the rotary body, and parallel cleaning parts coupled to the rear portion of the outer periphery of the rotary body; and a handle member coupled to the rear portion of the rotary member in such a manner as to be adjusted in length in a telescoping manner, whereby the slant portion and the parallel portion formed on the internal peripheral surface of the cartridge chamber are all cleaned at the same time.

Abstract: A charging handle assembly for an assault rifle includes a bolt engagement arm having an axially elongated shaft extending between a forward end and a rear end, a manual operator adapted to be manipulated by a user for effecting sliding movement of the bolt engagement arm, an operator extension elongated in the axial direction, connecting the manual operator with the rear end of bolt engagement arm and holding the manual operator forwardly thereof and laterally separated from the bolt engagement arm, an engagement latch mounted to the manual operator so as to be movable between an engagement position and an disengagement position, a biasing element extending between the manual operator and the engagement latch and biasing the engagement latch into the engagement position. A latch retainer can be attached to a mounting rail for receiving the engagement latch.
