A projectile which can be used to defeat an unmanned aerial system. The projectile features sabots which do not impart any forward impedance to the sub-projectiles, and carries a payload of stacked rings enclosed in the projectile. The rings are backed by a support ring, and abut a pusher aft section. The projectile's sabots discard cleanly upon muzzle exit, releasing the ring sub-projectiles to cover a large area, thereby increasing the probability of impacting the target. The rings create large holes in the target, despite comparatively low mass of a given ring as a defeat element, allowing for multiple sub-projectiles to be fired with a single shot, thereby creating the effect of firing multiple projectiles with a single shot.

A hand carryable, non-lethal personal protection device using compressed gas for operation. In some embodiments the device uses the compressed gas to create and shoot a vortex of air at the target. In other embodiments, the compressed gas can be used to shoot a burst of atomized water at the attacker. In still other embodiments the device uses the compressed gas to shoot ammunition, such as a ring airfoil, O-ring, bean bag, or other non-lethal blunt trauma munitions at the target. In still further embodiments, the device is modular in its construction, and can be used to apply the compressed gas to various different attachments.

The invention is an annular arrow fletch arrow stabilizer are therefor provided. The annular arrow fletch is used for; stabilizing arrow flight, providing better clearance and functionality then conventional fixed glued tail feathers, the invention can be used with light emitting diode arrow nocks. The invention improves current arrow shaft stabilization technology with reduced assembly labor cost, the elimination of facial and or face mask interference issues providing more clearance, improved accuracy, repeatable production with the consistent injection mold production of the annular arrow fletch, easy replacement of the annular arrow fletch in the field, and improved arrow storage. The annular arrow fletch incorporates a metallic contact point, which will work with all light emitting nocks. The design of the annular arrow fletch is so that it is affixed to an arrow by an arrow nock and comprises of an annular wing, a central elongated cylindrical cylinder with a cap and a plurality of fins with micro-groves and a metal contact. In use, the annular arrow fletch is affixed at the aft end of the arrow by an arrow nock prior to launch.
