GOLD TIP BLACK LABEL QUANTUM SHAFTS 300 1 DOZ. Gold Tip's Quantum is built for freight train penetrations, and with micro-diameter .204 design, it lessens the sideways drift compared to larger-diameter arrows. Add the night renegade graphics, and you have a subtle look matched with Gold Tip's legendary performance. The convergence of laser straightness, unmatched toughness, and micro-diameter penetration, the Black Label Quantum has performance that flat out kills.
