A projectile and stabilizer therefor are provided. The sliding stabilizer is used instead of fixed or glued tail feathers, vanes or other fletching as a means for stabilizing projectile flight. The invention improves current projectile technology with reduced assembly labor cost, the elimination of bow clearance issues, improved accuracy with the consistent production of the sliding stabilizer, easy replacement of the stabilizer in the field, and improved projectile storage. A sliding stabilizer is designed to slide along the shaft of a projectile and comprises a circumferentially extending wing and a plurality of fins. In use, the stabilizer is positioned at the front of the projectile prior to launch, and the projectile slides quickly through the stabilizer until secured at a stop position at or near the trailing end of the projectile. An annular arrow fletch and arrow stabilizer are also provided. The annular arrow fletch may be used for; stabilizing arrow flight, providing better clearance and functionality then conventional fixed glued tail feathers. A stabilizer may be used with light emitting diode arrow nocks. The stabilizer may improve 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. An annular arrow fletch may incorporate a metallic contact point, which will work with all light emitting nocks. A design of an annular arrow fletch may be affixed to an arrow by an arrow nock and may comprise 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.

A dart with a telescopic tail wing composes a dart rod, a dart head disposed at a front end of the dart rod and a tail wing disposed at a rear end of the dart rod. A tail wing connecting part is disposed at the rear end of the dart rod. The tail wing comprises a sleeve and multiple wing blades disposed on the sleeve. A clamping part is disposed on the tail wing connecting part. A limiting part is disposed in the sleeve. The tail wing connecting part is inserted into the sleeve. The clamping part stretches from one side to the other side of the limiting part and is matched with the limiting part. An elastic piece is disposed around the tail wing connecting part. The tail wing can rotate on the tail connecting part and can telescopic. In case of a collision, the tail wing can rotate to reduce force, so that compared with the prior art, dart is simple in structure, easy to assemble and low in production cost.

A toy arrow projectile for use with a toy projectile launching assembly is disclosed. The toy arrow projectile includes a shaft including a front end and a tail end, a pair of hook elements extending outwardly from the front end, a safety-tipped toy arrowhead attached to the front end, and arcuate fletching attached to the tail end. The pair of hook elements are configured to engage launching elements of the toy projectile launching assembly to stretch the launching elements therewith. The fletching includes arcuate fins extending along the shaft towards the front end. The arcuate fins include curved surfaces that curve outwardly from the shaft and generate spin in the toy arrow projectile during flight. The fletching includes a cross-sectional diameter having a distance that is less than the distance between the launching elements to allow passage of the toy arrow projectile through the launching elements without obstruction thereby.
