This JBL shaft is for AB-Biller 54 Custom and JBL (JBL4D50) Spearguns. The JBL7548S shaft is 48" (1,219 mm) long with a 5/16" (8 mm) diameter. Having spare parts for your gun or sling is the only way to assure you won't get skunked on a spear fishing trip. Constructed of corrosion resistant 17-4 (spring) stainless each shaft is hand-tuned for alignment then heat-treated for maximum hardness to reduce flex and provide optimum energy transfer.
OEM shafts for JBL and AB-Biller mechanisms are milled to spec for a perfect fit and function. Adapt-A-Shafts are 6mm threaded on both ends and accept 303 stainless adapters allowing you to customize length for just about any speargun mechanism available.
