Your best shot is only as good as the shaft you’re using.  Each JBL Reaper Shaft is individually hand tuned for straightness in our Oceanside shop before being heated to over 900 degrees Fahrenheit and allowed to cool slowly.  By using 17-4 stainless steel and heat treating, our shafts offer unparalleled durability and accuracy.
