Featuring 120-gram tri-wrapped unidirectional carbon fibers, and 120-degree seam manufacturing process for maximum hoop strength, superior component fit and consistent spine. Horton's Matched-Weight components optimize balance and accuracy. Available with feathers or vanes. Available in 3,6 or 72-packs. Length: 20". Weight (with 100-grain point): Feathers 426 grains, Vanes: 442 grains. Straightness Tolerance: +/- .003 at 20". Although the performance characteristics of crossbows are different from those of compound bows, most arrow companies build crossbow arrows using run-of-the-mill archery components with a "one-size-fits-all" approach. Horton's secret is in our Matched-Weight components which optimize the arrow's front-of-center (F.O.C.) weight distribution for maximum accuracy. Horton Carbon Strike arrows also feature an exclusive, laser-controlled EXP-120 degree carbon arrow manufacturing process that guarantees consistent arrow spine, manufactured to Horton specifications for distribution.
