The revolutionary McKinney II shaft allows archers to reach their maximum distance with less poundage than ever before!  This .167 ID, extremely fast arrow will give you speed beyond your wildest dreams.  With speed comes flat trajectory and flat trajectory  allows less wind drift.  Rick spent over three years working on the precision required to satisfy archers who want ultra-precise and ultra-fast products.  The super high tech, space-age carbon used in each shaft allows for the lightness with extreme exactness. The McKinney II shafts are the most precise arrows shafts made today.
