20-INCH / 415-GRAINS / BALANCED AT 13% FOC / .004" STRAIGHTNESS
3 Pack with Alpha-Blaze Lighted Nocks.
The Alpha-Blaze Lighted Nock contains a one-piece Nock/LED unit that is indexed with the vanes and press fits into the arrow's Aluminum Bushing. Upon firing the crossbow, the bowstring's force compresses the two pieces and activates the lighted nock.
Deactivate the easy on/off Alpha-Blaze lighted nock by pulling the nock straight out until the light turns off no tools are required. The LED light of the Alpha-Blaze system lasts for approximately eight hours when activated.
The system features TenPoint's Alpha-Nock HP and is equipped with an HP Aluminum Bushing for increased strength and accuracy. Weighing 415 grains, the Match 400 Carbon Crossbow arrow features a Stainless-Steel Insert which creates an improved 14% FOC, generating up to 20% tighter groupings than previous carbon arrows.
Each Match 400 carbon crossbow arrow is inspected for straightness to within .004". TenPoint's Alpha-Nock features a deep bowstring groove, a large smooth radius base, and elongated ears. The string on TenPoint's crossbows wraps tightly around the center of the Alpha-Nock to yield straight nock travel and precision down-range accuracy, while minimizing string serving wear. The Alpha-Nock's deep groove holds the bowstring in place on extremely narrow crossbows to prevent shoot-over or shoot-under.
