Repair your Sting bolts instead of replacing them. These BALLISTA half-moon nocks are made specifically for Sting micro-diameter bolts with 4.2mm ID / 6mm OD shafts, helping customers restore worn or damaged arrows and keep them in use longer. The half-moon shape supports proper string alignment, while the lightweight 2.5-grain high-hardness plastic construction helps maintain reliable bolt performance. Compatible with both 2-vane and 3-vane BALLISTA Sting bolts.
