Carbon Express Nano-Pro RZ Shafts 600 1 doz.

Designed for compound archers shooting long distance field and target archery. Parallel designed shaft has three different spines, with a more flexible center Red Zone and stiffer front and back sections. This manages how an arrow flexes in flight to deliver pinpoint accuracy.
