Your accuracy is only as good as the shaft you choose. Each JBL Spearshaft is meticulously hand-tuned for straightness at our Oceanside facility, then subjected to temperatures exceeding 900 degrees Fahrenheit and allowed to cool gradually. Crafted from 17-4 stainless steel and heat-treated, our shafts provide unmatched strength and precision.
