The next evolution in the Day Six arrow line is the XD series shafts. This 5mm shaft
has a lighter gpi than our HD shafts for those who want flatter trajectory or higher
FOC. Unlike all other 5mm shafts that come with a cheap insert or outsert, the XD
shafts come standard with our patented Centric System components as well as a ma
chined nock bushing to reinforce both the front and the rear of the shaft. Just like our
HD series shafts, the XD is made to the same tight tolerances to provide for precision
tuning and accuracy.
