Easton 4mm Avance Sport Shafts 660 1 Doz.

The Easton 4mm Avance Sport Shafts 660, sold by the dozen, are engineered for competitive archery and tactical field applications where precision and consistency are non-negotiable. Designed for shooters who demand repeatable accuracy, these shafts serve both traditional sport archery and professional applications requiring dependable arrow flight characteristics. Whether you're stocking equipment for a range, outfitting a competition team, or maintaining a professional inventory, this one-dozen bundle delivers the volume and quality that serious archers and tactical operators expect.

Built to Easton's exacting standards, the 4mm Avance Sport Shafts feature a 660 spine rating—a medium-weight specification ideal for bows in the 40–60 lb draw weight range with standard point weights. The 4mm outer diameter provides excellent arrow-rest clearance and reduced wind drift compared to larger-diameter shafts, translating to flatter trajectories and tighter shot groupings at distance. Easton's manufacturing process ensures uniform straightness and consistency across every shaft in the bundle, eliminating the performance variables that arise from mixed or lower-grade inventory. The straightness tolerance and spine consistency directly affect accuracy, making batch uniformity critical for both competitive and operational use.

This dozen-count package benefits competitive archers, club instructors, and professionals managing equipment logistics by reducing reorder frequency and ensuring consistent shaft performance across multiple shooting sessions. The 660 spine rating pairs optimally with recurve bows and modern compound setups in the mid-draw-weight category, making these shafts a reliable baseline for field testing, training programs, or backup inventory. Installation is straightforward—these bare shafts accept standard point weights and nocks, allowing customization to match individual bow configurations and shooting preferences. For organizations purchasing multiple dozens, batch consistency ensures that each replacement or training arrow maintains the flight characteristics of the original set.
