Abstract: A cartridge that generates higher than typical chamber pressures has an enhanced means of primer retention for retaining the primer in the primer recess of the casing. The means may be a lip folded onto a conical surface, a annular groove to receive deformed primer wall portion material upon detonation, a concavity in the rearward facing wall of the primer, a check valve in the flash tube to inhibit propellant gases from reaching the primer recess, or specifically configured primers with a greater length than diameter and with greater wall thicknesses.

Abstract: A method for inserting a safety block into a rifle comprising upper and lower receivers, the lower receiver comprising a trigger assembly positioned within a cavity. The method includes separating the upper receiver and the lower receiver to expose the lower receiver and inserting the safety block into the cavity. The safety block comprises a hammer cavity that surrounds the trigger assembly such that the safety block surrounds at least a hammer of the trigger assembly. A hammer stop of the safety block rests against the hammer. The upper receiver is then closed against the lower receiver. Closing the upper receiver brings the upper receiver into contact with the safety block and rotationally pushes the hammer stop of the safety block forward and against the hammer. Rotating the safety block against the hammer rotates the hammer to free the hammer from a restraining portion of the trigger assembly.

In other embodiments, a spring may be configured to bias the thumb support toward the extended position, and a stop structure may be configured to limit pivotal movement of the thumb support, such that liming pivotal movement of the thumb support defines the extended position.

Abstract: In one aspect, a sight with a momentary switch to control a laser beam on the sight may include a main power switch, a switch with momentary sensor, a plurality of locking screw to lock the sight onto a firearm, an orifice for emitting laser beams, a charging socket, and a laser adjustment screw. When in use, the user can press the main power switch to turn on the sight. In one embodiment, the switch with momentary sensor can emit infrared light and if the infrared light is deflected, the laser beam will be turned off. So, if the user wants to turn off the laser beam, the user can simply move the finger toward the momentary sensor to somewhat covers the momentary sensor to deflect the infrared light emitting therein.

Abstract: A gas-powered gun for discharge of projectiles, comprising a pressure chamber for holding compressed gas, a valve arranged to release compressed gas from the pressure chamber to thereby discharge a projectile provided in a barrel, and a plenum chamber in fluid connection with the pressure chamber. The plenum chamber is formed coaxially around a rear portion of the barrel.

Abstract: Improvements in a more efficient use of air in a projectile launcher is disclosed. The launcher uses a two-stage air gun fire and reset to have a more efficient compressed gas usage because the gas is not wasted by performing simultaneous actions, instead, the motion dedicates a portion of the motion to firing only then transitions a “port” to close and redirect the gasses to “re-cocking” without wasted gasses going out the firing bolt. The air is redirected through a moving port or gate to allow the launcher to continue to perform and “cycle” to the point where there is low pressure in the supply tank. This prevents chopping or shredding of paintballs because the feed port of the projectiles only partially opens. The improvement allows the launcher to reliably feed and fire projectiles down to the point where it is obvious that the tank requires changing.

Abstract: Various methods and devices have been invented to remove IEDs and tracking devices from substrates such as the body of vehicles. For example, highly localized heat can be used to denature strong magnets or weaken applied adhesives.
