How to Adjust Peep Sight on Compound Bow: A Step-by-Step Guide for Beginners

By Emily Parker

Updated November 2026

Learning how to adjust peep sight on compound bow setups comes down to three things: setting the peep height so your sight picture lines up with your eye, rotating the peep so it sits level, and fine-tuning the position with a small test group. Once you work through these steps, your sight pins will line up consistently at full draw. Expect the whole process to take 20 to 30 minutes if you have a bow press or a helper, and a bit longer if you are working alone.

What You Need Before You Start

Allen wrenches sized for your peep and sight housing (usually 1.5 mm to 3 mm)
A bow square or a level
A draw length measurement and a set of arrows already cut to length
A target at 10 to 20 yards and a rest or stable shooting position
Painter’s tape or a marker for noting adjustments

Step 1: Set the Peep Height

Start by drawing the bow to your normal anchor point with a relaxed, repeatable hold. Look through the peep and note where it sits relative to your eye. In most setups, the peep should sit so that the top of the sight ring frames the full sight window without forcing you to tilt your head.

To raise or lower the peep, loosen the string-level adjustment or peep-tying point and slide the peep up or down the string in small increments of about 1/16 inch. Re-check your anchor after each change. A peep that is too high makes you crane your head, while one that is too low forces your eye to drop below center.

Step 2: Level the Peep Rotation

A peep that tilts causes your sight picture to look skewed, which translates into inconsistent groups. Use a bow square or a level held against the bow’s limbs or cams to check the peep. Rotate the peep by turning it on the string, then tighten the knot or peep bushing so it stays in place under draw.

Many shooters find it helpful to make a single, final level check after the bow is fully tuned, because small changes in string tension can shift the peep slightly.

Step 3: Fine-Tune Through a Test Group

Shoot a group of three to five arrows at 10 yards, paying close attention to where the arrows land relative to the center. If your group sits high or low, adjust the peep height in tiny steps. If it sits left or right, check your nock point and rest settings before changing the peep, since peep position alone rarely fixes horizontal drift.

Repeat the process at 20 yards once your 10-yard group is tight. Small adjustments should be made one at a time so you can tell which change produced which result.

Common Mistakes

Adjusting the peep while your anchor point is inconsistent, which makes every change look like it worked or failed
Making large peep moves instead of 1/16-inch increments
Ignoring a tilted peep and trying to correct the group with sight pins alone
Forgetting to re-check the peep after changing draw weight or string length
Over-tightening the peep knot, which can slip or damage the string

Recommended Gear

A bow square helps you confirm peep level quickly and repeatably, which is useful for both initial setup and later checks. View on Amazon

A set of hex and Allen wrenches in small sizes makes it easier to loosen and tighten sight housings without stripping screws. View on Amazon

A peep sight tying kit or replacement peep bushing lets you rebuild a worn or slipping peep without replacing the whole string. View on Amazon

FAQ

How often should I check my peep sight adjustment?

Check it whenever you change draw length, string, or arrow setup, and at least once a month if you shoot regularly. String stretch over time can gradually move the peep.

Can I adjust the peep sight without a bow press?

Yes, but you will need a helper or a way to hold the bow steady while you check the peep and adjust the string. Use a bow stand or a sturdy surface to keep things stable.

Why does my peep keep slipping out of place?

A slipping peep usually means the knot is not tied tightly enough or the peep bushing is worn. Re-tie the peep with a secure knot and replace the bushing if it no longer grips.

Conclusion

Setting the peep height, leveling the rotation, and fine-tuning with a short test group will get your sight picture consistent. Make one change at a time and keep your anchor steady so you can read the results clearly. If you run into persistent problems, a local archery shop or certified bow technician can check your setup in person.
