The Gold Tip Kinetic Pierce is a micro diameter shaft that's built to hunt. Its greatly reduced diameter makes it resist wind drift for long range accuracy. Its decreased weight makes it fly fast and flat. And when the Pierce impacts its target, it has the energy to punch through. Thanks to the patent pending Ballistic Collar Insert System, this surgical arrow has the strength to take on any hide, meat, or bone you put in front of it.
