BLOCK®, the most popular archery target on the market, introduces the BLOCK Infinity Crossbow. Built around a reputation of long-lasting durability the BLOCK® Infinity locks in a new level of extreme stopping power specifically designed for today's high-energy crossbows and extended target life with exclusive construction and six-sided shooting. Leveraging the proven stopping power of BLOCK's PolyFusion™ Technology BLOCK Infinity Crossbow 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 bolt removal. This exclusive technology allows the exterior face to assist in slowing bolts, while letting them find a path between the internal layers to stop with friction and not force. The six-sided exterior features six individual shooting faces with five unique designs strategically-placed to offset aiming areas for extended target life and maximum durability. Safe for use with field points and both fixed and expandable broadheads and guaranteed to stop standard diameter bolts up to 520 F.P.S.! Two versions are available; the BLOCK Infinity Crossbow 16 measuring 16”x16” and BLOCK Infinity Crossbow 20 measuring 20”x20”.
