The Carbon Express Maxima Red OD Green Shafts are engineered to deliver unmatched accuracy by expertly managing Dynamic Spine, the way an arrow flexes in flight. Featuring a breakthrough design, these high-tech carbon arrows have stiffer ends that contain flex within the RED ZONE, a specific section of the shaft engineered to enhance broadhead performance. By reducing the flex in the front of the shaft, the Maxima RED arrows ensure tighter groups and superior hunting performance, making them the best mid-weight hunting arrows available. The Maxima Red OD Green Shafts are the perfect choice for hunters seeking precision and reliability in the field.
