If you have the AB Biller Speargun Model SM 42, ST 42, SP 42, LTD (Mahogany, Padauk, or Teak) 42, or SS 42, then you’ll need some spare spear shafts to go with it! The AB Biller Spear Shafts are made from military-grade spring steel alloy that has been heat treated to Rockwell 44C steel. The material used possesses a seemingly perfect balance between hardness and spring tension. The 3 grooves along the shaft accommodate up to 3 spear bands, and the 6mm threading allows you to attach nearly any spear tip you’d like to use at the end.
