Tenpoint Crossbow Discharge Arrow Features The Tenpoint Crossbow Discharge Arrow is built from carbon fiber for a lightweight yet durable shaft that can withstand repeated discharging without cracking or splintering. At 20 inches long and 725 grain the arrow carries enough mass to properly absorb the crossbow s stored limb energy which protects the riser limbs and cables from the stress of an unloaded or dry fire shot. This makes it an essential safety accessory for anyone who cocks a crossbow and later decides not to take a shot since safely discharging the bow is critical to protecting the equipment. The Universal Alpha Nock on the rear of the shaft is designed to seat consistently on the string for a reliable repeatable discharge every time it is used. Because it ships as a single arrow rather than a full hunting set it is purpose built for this one task rather than for target practice or hunting accuracy. Crossbow owners who regularly cock and de-cock their bow in the field will find this a simple inexpensive way to protect their investment. The Tenpoint Crossbow Discharge Arrow is a practical purpose-built accessory for any crossbow hunter s gear bag.
