ABSTRACT:
A guide ring for a broadhead encircles an arrow shaft and is frictionally held at the tail edges of the broadhead's blades. The guide ring has a smaller inside diameter at its rearward edge than at its forward edge to deflect air inwardly toward the arrow shaft. The smaller inside diameter is also sized to be larger than the arrow shaft which it encircles to provide space for air to flow between the guide ring and the shaft. Notches on the forward edge of the guide ring frictionally grip the tail edges of the broadhead blades to hold the guide ring in position during the flight of an arrow. When the arrow is in flight, the shape of the guide ring smoothly directs air toward the arrow shaft to increase the airflow past the arrow fletching for increased stability of the arrow. When the broadhead penetrates a target deeper than the tail edge of the blades, the guide ring is forced rearward away from the blades by the target material contacting the forward edge of the guide ring. The guide ring then slides easily backward on the shaft so that it can be repositioned on the blades again whenever the arrow is reused.
