These features translate into real-world performance: the 6mm reduced diameter reduces air resistance and helps maintain velocity, while the carbon-fiber construction provides a stiff, responsive shaft that resists bending under field conditions. The factory helical fletching stabilizes the arrow quickly after release, delivering tight groupings at typical hunting and target ranges. Pre-installed nocks and inserts cut setup time and ensure precise overall arrow balance, so your shots stay consistent across practice sessions and competitions. The Sonic 6.0 340 is particularly versatile, offering multiple spine options (250–600) to help you tailor spine to your draw length and draw weight. This makes it an excellent choice for shooters who want reliable, out-of-the-box accuracy with a high-quality, field-ready carbon shaft.
