Measuring 20 inch in length, weighing 445 grains, & featuring 15.5% FOC, the CenterPunch HPX is spine-aligned to the odd color vane & is TenPoint's most accurate 20a ^2 arrow. Each arrow is inspected for straightness to within .001" and each package is weight-grain matched within 1 grain per arrow. Featuring a unidirectional carbon inner layer for stiffness, and a woven carbon fiber outer layer for impact strength, the arrow is equipped with the patented Alpha-Nock HPX. The NEW Alpha-Nock HPX features a Nock Retention Groove that snaps into the TriggerTech trigger box on the TRX 515 & TX 440 allowing the user to both hear & feel the positive engagement of the nock to the string-indicating your arrow is properly locked & loaded in the crossbow. In addition, the "snap-in" design of the Nock Retention Groove eliminates the fit disadvantages & string wear associated with "snap-on" nock designs.
