The Instinct arrow is the only wood-grain-micro-diameter-carbon-traditional arrow on the market today. Designed to be more shootable, the Micro-Diameter size helps to offset the off-center design of most recurve and longbow risers made today. We also coupled the Instinct with super tough Stainless Steel outserts, that weigh 100 grains, so you can have the weight up front where you want it.
