Tenpoint ACU-X RD Features The TenPoint ACU-X RD arrows use a precision spine-indexing manufacturing technique that places each arrow s spine in the exact orientation tested to perform best specifically on rail-less reverse-draw crossbows. This attention to spine alignment delivers the consistency and long-range accuracy serious crossbow hunters expect from their equipment. Each 20 carbon shaft is matched with a 92 grain insert producing a 16.5% front of center balance that improves flight stability and downrange accuracy. Every arrow is inspected for straightness to within .001 and each three-pack is weight-grain matched within 1 grain per arrow for consistent performance across the set. The ACU-X Snap-On Lighted Nock is engineered to provide an unmistakable audible click when properly engaged with the bowstring eliminating lateral nock travel during the shot cycle for tighter groups at extended range. Upon firing the bowstring pushes the nock fully into its bushing activating an LED light that lasts approximately 24 hours and helps hunters track arrow flight and locate a hit animal. TenPoint pairs this nock system with 2 Blazer vanes a vane renowned across archery disciplines for delivering reliable shot-to-shot consistency. At a total weight of 440 grains including a 100 grain field point the TenPoint ACU-X RD arrows are available for sale at GrabAGun for hunters running rail-less reverse-draw crossbows who demand precision at distance.
