BLOCK introduces theBLOCK Infinity Crossbow. Built around a reputation of long-lasting durability the new BLOCK Infinity locks in a new level of extreme stopping power and extended target life with exclusive construction and six-sided shooting. Leveraging the proven stopping power of BLOCK's PolyFusion Technology BLOCK Infinity targets are constructed around a high-density layered-foam inner core encased with an exterior foam wall that delivers extreme stopping power and exceptional durability, while still offering easy arrow removal. This exclusive technology allows the exterior face to assist in slowing arrows, while letting them find a path between the internal layers to stop with friction and not force.
