TENPOINT ACU-X NOCK 12PK

The ACU-X Snap-On Nock provides the most consistent design for rail-less crossbows and preserves string life. - Our innovative Snap-On design provides an audible click when properly engaged with the bowstring. - By providing a secure string fit the Snap-On design eliminates lateral nock travel during the shot cycle for precision long-range accuracy. - NOTE: The ACU-X Snap-On Nock is required for use with TenPoint Rail-Less Crossbows. Failure to do so will void the manufacturers warranty.
