Your accuracy is only as good as the spearshaft you use. Every JBL Spearshaft is meticulously hand-tuned for straightness in our Oceanside facility, then subjected to intense heat over 900 degrees Fahrenheit and allowed to cool gradually. Crafted from 17-4 stainless steel and undergoes heat treatment, our shafts provide unmatched durability and precision.
