Carbon Express Nock Collars Tank 23d 350/x-buster 400 12 Pk.

The Carbon Express Nock Collars Tank 23d 350/X-Buster 400 12 Pack provides essential protection at the nock end of precision archery shafts. Designed for competitive archers, hunters, and recreational shooters, these nock collars absorb impact energy during arrow nocking and target contact, preventing stress fractures that can compromise arrow integrity and flight consistency. This 12-pack offers excellent value for archers who regularly replace worn collars or maintain multiple arrow setups.

Carbon Express engineered these nock collars to reinforce the shaft's weakest point—the nock end—where repeated impacts from the bowstring and target contact create micro-fractures over time. The collars fit both 350 and 400 spine weight shafts, accommodating a wide range of draw weights and arrow configurations. By distributing impact force across a wider surface area, the collars extend arrow lifespan and maintain critical dimensional tolerances that affect arrow spine, grouping accuracy, and downrange performance. The durable composite construction resists splitting while remaining lightweight enough to preserve arrow dynamics.

Archers utilizing Carbon Express shafts in the 350 and 400 spine categories will find these collars essential for both indoor league shooting and field applications. Installation is straightforward—simply slide the collar onto the nock end of the shaft and secure according to Carbon Express specifications. Whether you're building a fresh dozen for tournament season or refreshing an aging quiver, this 12-pack supply ensures you maintain optimal arrow condition across your complete setup without frequent reordering.
