Carbon Express Nock Collars Tank 23d 400/x-buster 500 12 Pk.

The Carbon Express Nock Collars Tank 23d 400/X-Buster 500 12 Pack provides essential protection for the nock end of your arrow shafts during high-impact shooting scenarios. Designed for archers who demand reliability and durability, these nock collars serve as a reinforcement system that guards against the most vulnerable point of an arrow—where nock failure can occur from repeated impact with bow components or accidental contact during transport and storage. Whether you're a competition archer, hunter, or recreational shooter, this 12-pack ensures you have adequate replacements on hand to maintain consistent arrow integrity across your quiver.

Carbon Express engineered these nock collars to absorb and distribute impact forces away from the nock seat, significantly reducing crack propagation at the shaft's end. The Tank 23d profile is optimized for Carbon Express shafts in the 400 and X-Buster 500 spine classifications, offering a precise fit that prevents lateral movement while remaining lightweight enough to avoid affecting arrow flight dynamics. The protective collar design reinforces the structural integrity of the nock end, extending the serviceable life of expensive arrow shafts by preventing premature retirement due to stress fractures or split wood grain around the nock.

Archers using Carbon Express 400 or X-Buster 500 shafts will find these collars essential for long-term arrow maintenance and cost efficiency. Installation is straightforward, requiring only a firm press onto the nock end of compatible shafts—no tools or adhesives necessary. The 12-pack quantity provides multiple replacement sets, making this an economical choice for serious archers who shoot frequently and want to protect their investment in quality arrow components.
