TenPoint Alpha-Nock HPX with Nock Retention Groove

The Alpha-Nock HPX features a revolutionary Nock Retention Groove that snaps directly into TriggerTech trigger boxes on TRX 515 and TX 440 crossbows. This design provides audible and tactile feedback to confirm proper arrow engagement, ensuring your arrow is securely locked and loaded. The snap-in design eliminates fit issues and string wear associated with traditional snap-on nock designs, while the HP aluminum bushing increases strength and durability for consistent performance.
