Abstract: A firearm stock adjustment device for attachment to a firearm stock provides for a consistent, stable cheek weld and improves speed and consistency for an aimed shot. The device includes a thickness that fills and empty space between the maxilla and the front of the mandible with the firearm stock during a cheek weld and provides rest to the zygomatic arch and bone and pushes the firearm outward away from the jaw and tilts the head more vertically. This provides a quick and consistent sighting with the firearm when the cheek weld is performed and reperformed. The device is disposable, lightweight, cost effective, and comfortable and is universally attachable to common rifle stocks.

Abstract: User-zeroable adjustment knobs for an aiming device include a rotating member that is rotated to change a setting of the aiming device, a dial selectively couplable to the rotating member via a clutch for co-rotation therewith, and a locking mechanism that prevents the dial and rotating member from rotating relative to the aiming device when the locking mechanism is locked. The clutch is disengageable 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 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.

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.
