Clean-Shot Archery was founded in 2009 when a failed hunting trip in the very wet Pacific Northwest got company founder, Larry Bay, thinking about products that would help bowhunters make more accurate, Clean-Shot. By using some of the most cutting edge technologies on the market and having the capabilities to have a truly universal fitting, the lighted arrow Nock Out illuminated nocks are the first of their kind and will change the way that the archery industry pictures them. New for 2016 is Nock Out's Chameleon color changing nock. Be sure to check out the video in the product page that goes into details about how to use and what exactly it is! Shoot Straight and aim small!
