The KingsArchery 80lb Self-cocking Crossbow features a self-cocking system that helps making shot after shot quick and easy. The package itself already comes with 3 aluminium arrow bolts, but this set will include a two bonus 12-packs of aluminium arrow bolts to give you a total count of 27 aluminum bolts! There is also a adjustable sight to help you place your shots on your target. The bow limb is made of durable compressed fiber glass. The convenient self cocking lever makes it safe and easy to use while allowing you to reload your arrows more quickly allowing you to fire shot after shot just like that. As always, remember to wax your strings and check to make sure the screws are tightened as they can become loose over time. This product is also eligible for KingsArchery's life-time technical support and manufacturer's warranty. To string the bow limb at ease, we recommend you to get a Bow Stringer.
