Abstract: A quick release stock assembly for a launcher is provided having a stock bar and a stock housing. The stock bar has a first end and a second end, the first end having a mating member that secures the stock bar to the launcher in a first orientation and that precludes the stock bar from being removed from the launcher in the first orientation. The stock bar is removable from the launcher in a second orientation. The stock housing has a cavity sized to receive a pressurized canister, and a receiver to slidingly receive the stock bar about its length. The stock housing further has a release pin transverse to the receiver to engage the stock bar and longitudinally fix the stock bar in the stock housing in a plurality of positions.

Abstract: A magazine for a projectile launcher is provided. The magazine has a housing having a cavity to retain a plurality of frangible projectiles, a follower and spring to engage and push the projectiles through the cavity, and feed lips extending from the housing. The magazine also has an opening to allow a projectile to be ejected from the housing and to remain engaged by the feed lips when the magazine is connected to the launcher. When the magazine is connected to the launcher the feed lips engage the barrel of the launcher and the projectile is placed in the barrel breach but the projectile remains associated with the feed lips. However, upon removal of the magazine from the launcher the projectile that was in the barrel breach remains with the magazine.

Abstract: Attachments for adjusting optical properties of image forming optical systems. An example refocus flip optic adaptor for a night vision goggle may include an adaptor housing for detachably mounting to an objective lens assembly of the night vision goggle and an optical element holder pivotably mounted to the adaptor housing such that a refocus lens (or other optical element) mounted to the optical element holder is selectively positionable in an operative position in which the refocus lens is axially aligned with the objective lens of the night vision goggle and an inoperative position in which the refocus lens and the optical element holder do not affect an image viewable through the night vision goggle. In some example embodiments, the optical element viewing diameter may be substantially the same as objective lens viewing diameter. Example optical elements may affect optical properties such as objective lens focus, optical filtering, and magnification.
