Hunters, here's a serious arrow built for speed and penetration. The Gold Tip Pierce is a micro-diameter shaft, which means it's thinner than standard arrows. Why does that matter? Less wind drift for better long-range accuracy, and less surface area for deeper penetration on impact. They're lightweight so they fly fast and flat. The secret sauce is the patent-pending ballistic collar insert system, which reinforces the front end to withstand bone and tough hide without breaking. Each dozen set comes ready with GT nocks, nock collars, and the ballistic inserts. They have a tight straightness tolerance of +/- .006 inches and a weight tolerance of +/- 2 grains. Available in different spine sizes (250, 300, 340, 400, 500) to match your bow's draw weight. If you want a tough, accurate arrow for big game, the Pierce is a top choice.
