Our new AR-6 Stinger PRO limb, constructed of fiberglass and carbon fiber, boasts a significant boost in power compared to standard limbs. Depending on arrow weight and string setup, this limb delivers between 13.3 and 15.5 foot-pounds of kinetic energy. This limb is compatible with all replacement strings for the AR-6 Stinger I and II. Note: It is highly recommended to use this limb only with Bodkin arrows or broadhead arrows to increase longevity of the limb tips, string and limb itself. These limbs do not fit previous versions of the AR-6 Stinger. The 90-pound draw weight is not a reliable indicator of performance.
