Tenpoint Tenpoint Hea-779.3 Centrpnch Hpx Ab Crb 20.001 Rd

The TenPoint CenterPunch HPX is TenPoint's most accurate 20-inch crossbow arrow, built for hunters and serious field archers who demand precision and visibility downrange. This 3-pack of lighted arrows combines proven carbon construction with TenPoint's Alpha-Blaze HPX lighted nock system, giving you the edge in low-light hunting conditions and the confidence that every shot is locked in and ready to fly true.

Each arrow is engineered for accuracy and consistency: measuring exactly 20 inches and weighing 445 grains, the CenterPunch HPX features a 15.5% forward of center (FOC) balance optimized for crossbow performance. Every arrow is hand-inspected to .001-inch straightness, and all three arrows in the pack are weight-grain matched within 1 grain of each other—meaning uniform flight and repeatable point of impact from shot to shot. The arrow's dual-layer carbon construction uses a unidirectional carbon inner core for stiffness and a woven carbon fiber outer layer for impact durability, so it can handle the demands of field hunting and practice.

The patented Alpha-Nock HPX is the real innovation here. Unlike older snap-on designs, this nock features a Nock Retention Groove that snaps positively into compatible TenPoint trigger boxes (such as the TRX 515 and TX 440), giving you both audible and tactile feedback when the arrow is properly seated and locked. The result is repeatable nock engagement, consistent string travel, and less wear on your crossbow's serving. The nock itself sports an HP aluminum bushing for added strength, a deep bowstring groove, and a large smooth radius base that keeps the string centered and pulling straight every time you fire.

Visibility matters in the field, and the Alpha-Blaze HPX lighted nock activates automatically when the bowstring pushes it fully into the bushing on release. The LED burns for approximately 24 hours per activation, making your arrow easy to track in flight and spot in the field—especially valuable in low-light hunt windows. Deactivation is simple: grip and pull the nock straight out until the light goes dark.

Specifications

Frequently Asked Questions

What crossbows are these arrows compatible with?

The Alpha-Nock HPX with Nock Retention Groove is designed to snap into compatible TenPoint trigger boxes, including the TRX 515 and TX 440. If you own a different crossbow model, confirm compatibility with your manual or contact TenPoint directly, as the nock engagement system is specific to certain trigger designs.

How do I activate and deactivate the lighted nock?

The Alpha-Blaze HPX lighted nock activates automatically when you fire the crossbow—the bowstring pushes the nock fully into the bushing, which turns on the LED. To deactivate it, grip the nock and pull it straight out with your fingers (or use a Bednar Perfect Puller, sold separately) until the light goes dark. The LED lasts approximately 24 hours of active use per activation cycle.

How straight are these arrows, and are they weight-matched?

Each arrow is inspected for straightness to within .001 inch—among the tightest tolerances in the industry. All three arrows in the pack are weight-grain matched within 1 grain of each other, ensuring that they fly identically and group consistently downrange. This level of quality control is critical for repeatable accuracy from a precision crossbow.

What makes the Alpha-Nock HPX different from older snap-on nocks?

The Alpha-Nock HPX features a Nock Retention Groove that snaps positively into the trigger box, giving you both audible and tactile feedback that the arrow is properly locked and loaded. Unlike traditional snap-on designs, this snap-in approach eliminates fit inconsistencies and reduces string wear, resulting in more consistent nock travel and tighter accuracy. The nock also includes an HP aluminum bushing, deep bowstring groove, and large smooth radius base to keep the string centered and pulling straight every shot.
