Tenpoint CenterPunch HPX Features The Tenpoint CenterPunch HPX is engineered as TenPoint s most accurate 20 inch arrow spine-aligned to the odd colored vane for consistent flight every shot. Each arrow measures 20 inches in length and weighs 445 grains delivering 15.5 percent front of center weight distribution for stable accurate downrange performance. The unidirectional carbon inner layer provides stiffness while the woven carbon fiber outer layer adds impact strength giving the arrow durability shot after shot. Every arrow is inspected for straightness within .001 inches and weight-grain matched within 1 grain per arrow ensuring exceptional consistency across the entire 6-pack. The patented Alpha-Nock HPX features a Nock Retention Groove that snaps directly into the TriggerTech trigger box on TenPoint s rail-less crossbows such as the TRX 515 and TX 440 letting the shooter both hear and feel positive engagement of the nock to the string. This snap-in design eliminates the fit disadvantages and string wear associated with older snap-on nock designs. An HP Aluminum Bushing adds strength and accuracy to the nock while a deep bowstring groove and elongated ears help the string wrap tightly around the nock for straight travel. Finished with 3 inch Bohning X Vanes in red the Tenpoint CenterPunch HPX is for sale at GrabAGun for crossbow hunters who demand precision downrange accuracy from their arrows.
