The Nitro Peep Sight is made from high-impact resin which will provide years of worry free use. This self-aligning peep sight eliminates the twisted peep upon draw so you are sure to be ready when the moment of truth arises. The premium Silicone Peep Tubing (included) assures that you will eliminate the dry rot and cracking that is so common with other tubings. With the color matched tubing, your bow will have a custom look that will add to the style of your bow package. MADE IN USA.
