Look for the green line—the all-new Delta McKenzie Greenline block-style target is built to last. In head-to-head shooting tests, results show new Greenline will last up to two times longer, which greatly extends target life on the archery range. The foundation of Greenline's durability is its exclusive heavy-duty Mo'Foam layers. In addition, Greenline uses Delta's patented process that welds the layers together into a single block. The resulting solid target offers four-sided shooting and further extends durability.
