The present invention relates to the improved feathers of an arrow, and more particularly, to the improved feathers of an arrow, which prevent instability of flight caused by a vortex generated during the flight of the arrow by forming a plurality of arrow feathers attached to the arrow, which has a cross section which is a curved surface and integrally forming an auxiliary surface having one surface which is the curved surface with the arrow feather to guarantee stable flight.

The device of the present disclosure is a weapon. The weapon having a CO.sub.2 powered projectile which is fired from the weapon, used principally for self-defense. The projectile is generally rocket shaped wherein the front end of the rocket can be formed by a rounded shape of a front of a CO.sub.2 cylinder. The impact of the rocket projectile on a human could cause some pain, depending upon exactly what part of the body it hits. The impact could also cause some loss of balance to a human, due to the impact.

A cylindrical carbon fiber arrow shaft formed with an exterior surface having single or multiple outside diameters and formed with an axial bore having multiple interior diameters. In a preferred embodiment, the exterior surface of the arrow shaft has an increased external diameter at the nock end and tapers to a smaller external diameter at the tip end. The axial bore has an internal diameter at the nock end corresponding to standard arrows having external diameters of 0.295 inches and tapers to a smaller internal diameter at the tip end. Modifying the length, diameter, and wall thickness of the arrow shaft varies the stiffness of the arrow shaft along the length and shifts the center of gravity along the length of the arrow shaft and as well. Utilizing standard internal diameters, nock and tips may be attached without spacers or inserts, thereby decreasing weight of the arrow significantly.

Mechanically attachable fletching is disclosed herein for a projectile having a shaft having an exterior surface. The mechanically attachable fletching includes at least one fin, a connection section bordering the at least one fin, and at least one mechanical fastener for attaching the fletching to the exterior surface of the shaft via the connection section. Also disclosed herein are methods for mechanically attaching fletching to the shaft of the projectile. Also disclosed herein are illuminated projectiles. Also described herein is a projectile having a shaft, a projectile head, and at least one fin. The projectile head preferably has a plurality of layers, the head end preferably being associated with the projectile head. Also described herein is a projectile that includes a shaft, a suction head, an outer head casing, and at least one fin. The suction head is preferably associated with the head end. The at least one launcher engager is preferably associated with the suction head. Two halves of the outer head casing preferably sandwich the suction head and the head end.

A system for propelling an air-driven projectile from an air gun includes an air gun with an elongate bore and a source of compressed air in fluid communication with the elongate bore. A projectile is disposed within the bore of the air gun, the projectile having an outer diameter that is less than an inner diameter of the elongate bore.

An inventive system comprising a pistol crossbow, a blowgun, a first gas seal operatively associated with said blowgun, and a first pistol crossbow bolt selectively operatively associated with said pistol crossbow and said blowgun, said first pistol crossbow bolt configured to be capable of being selectively operatively interchanged between said pistol crossbow and said blowgun for elastic launching by said pistol crossbow and pneumatic launching by said blowgun. It may further be seen in view of this disclosure that within the scope and the spirit of the inventive disclosure and the claims appended hereunto are inventive system and method examples including, but not limited to, a method of driving a hardware fastener and/or providing a hardware fastener driving system, a system and method for a PPECS stabilizer acceleration interface, and a gas seal comprising a bulkhead and a label configured to be capable of being mounted to said bulkhead.

An assembly for launching toy projectiles includes a body having a bore, a plunger extendable from the bore, and a shaft removably attachable to the body. The body includes a first recess having a first diameter for receiving a first projectile. The shaft includes a second diameter for receiving a second projectile therearound and a second recess having a third diameter for receiving a third projectile therein. The first diameter is substantially equal to a diameter of the first projectile, the second diameter is substantially equal to a diameter of the second projectile, and the third diameter is substantially equal to a diameter of the third projectile but smaller than the second diameter. The plunger drives air through the assembly when released from an extended position to eject any one of the first, second, or third projectiles positioned in the first recess, on the shaft, or in the second recess.

In aspects of the invention, an arrow slide is provided with a body having a first opening with a plurality of first edges arranged in a generally triangular configuration within which a first diameter can be received, a second opening with a plurality of second edges arranged in the generally triangular configuration within which the first diameter can be received; sidewalls linking corresponding ones of the first plurality of edges to the plurality of second edges to create a passageway extending from the first opening to the second opening through which an arrow can slide; and a string mount to which a bowfishing line can be joined.
