Ravin .001 R500 Series Arrows have been designed specifically to match the high speed and high performance of Ravin R500 Series Crossbows featuring an incredible straightness tolerance of .001 (inclusive of 100-grain field tip or broadhead) for the uncompromising Apex Hunter. These durable arrows withstand the enormous kinetic energy of R500 bows while providing a smooth in-flight path that’s true to the target.
