The original open-layered archery target, The BLOCK® changed the way we all practice! The heat generated by the friction caused as the arrow slides between layers literally grabs and stops the arrow. This heat quickly dissipates, releasing the arrow! The first archery target to offer both easy arrow removal and long target life, regardless of arrow tip! Allows you to shoot broadheads/expandables all year long. Stops Field tips, broadheads and expandables.
