The BLOCK Invasion offers 4 sided shooting for increased target life. The BLOCK Invasion is 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 front and back are designed for broadheads and field tips while the sides are intended for field tips only.
