• Pin shafts with single barb
• Three-phase Rockwell stainless steel shaft, 6.7mm diameter
• 3 raised sections for hooking the shaft
• 1-mm thick long barbs along the entire length
• Stainless steel deflector standard
Benefits:
• Quality of the steel
• The contour of the raised sections makes it possible to mount the shaft on open or closed Beuchat muzzles.
• Stainless steel deflectors, unaffected by penetration of large prey, ensure perfect trajectory.
• Easy to load and safe to use
