How to Adjust a Peep Sight

The peep sight is an aiming tool attached to recurve and compound bowstrings. The sight narrows the field of vision and increases focus on the target. Peep sights are not necessary and modern pin sights are often used to replace the peep. The peep sight does work in conjunction with pin sights when properly aligned. Adjusting the sight is a simple process but you must be careful to avoid damage on the bowstring. Adjusting a peep sight is accomplished in less than one hour with few tools.

Instructions

    • 1

      Draw the bowstring into your normal firing position. You must use a consistent anchor point to prevent the peep sight from changing positions. Hold the draw position and have a friend mark your eye level on the string with a white pen.

    • 2

      Use a razor blade to remove the bottom serving thread if the peep sight is too high. Remove the top serving thread if the peep is too low. Remove the serving thread from the peep sight and slide the peep sight to the marked position.

    • 3

      Adjust the sight until the bowstring sits in the grooves on the sides of the sight. The peep will sit at a slight angle to compensate for the angle of the string at full draw.

      Cut a one-foot length of serving thread and wrap it around the circumference groove on the sight. Tie a single overhand knot and tighten it around the sight. Tie a second overhand knot and add a small drop of strong glue to the knot. Cut the extra serving thread away from the sight.

      Replace the section of serving thread you removed from the bowstring with a new section of thread. Cut a two-foot section of serving and wrap it around the bowstring. Tie a single overhand knot to begin the serving. Make a one-half wrap and tie a second knot on the opposite side of the string. Continue tying alternating knots towards the peep sight until you have 15 knots. Add a small drop of strong glue to the final knot and cut the extra serving thread from the bowstring.
