A plurality of angularly spaced fins are pivotally mounted on the body for rotating outwardly from an axial to an extended position. Each of these fins has a pivot point and a center of gravity. The center of gravity for each fin in the axial position is spaced radially inward from the pivot point. Slots formed within the projectile body aid in retaining the fins in their axial position.
