Tenpoint ACU-X Features The TenPoint ACU-X Premium Carbon Arrows use a precision spine indexing manufacturing technique that places the spine of each shaft in the exact orientation proven to perform best on TenPoint s rail less forward draw crossbows. This process delivers consistency from arrow to arrow which matters when every shot needs to land in the same group at extended range. Each shaft is built with a 92 grain brass insert giving the arrow a 16.5 percent forward of center balance for improved flight stability. The carbon composite construction keeps the arrows light and durable standing up to repeated impacts without losing straightness. The ACU-X Snap-On nock locks onto the bowstring with an audible click confirming proper engagement and eliminating lateral nock travel during the shot cycle that can rob accuracy. Industry leading 2 inch Blazer vanes are paired with the nock for consistent stable flight across a range of distances and conditions. Every arrow is inspected to a straightness tolerance of 0.001 inches and weight matched within 1 grain of its stated 440 grain total which includes the 100 grain field point. Crossbow hunters and target shooters running a TenPoint rail less forward draw platform will appreciate arrows purpose built for their exact system rather than a generic aftermarket shaft.
