The BLOCK® Invasion offers 4-sided shooting. A simple, yet revolutionary conceptualized product that has changed and set the standards for the way archers practice. The front and back of the BLOCK® Invasion target has an open-layered design that stops arrows with friction, not force. The patented friction layered design allows arrows to enter between open, unglued layers of friction foam. The heat generated by the arrow penetration, along with friction, causes the BLOCK® Invasion to grab the arrow shaft. In just a few seconds, the heat dissipates and releases the arrow shaft, allowing for easy removal. Specifically designed with high contrast graphics, which aid in visibility, for shooting longer distances and has multiple aiming spots that extend target life. The front and back of the target is designed for broadhead (fixed or expandable) and field tip arrows, while the sides are Polyurethane wrapped and are intended for field tip only arrows.
