If you feel confident enough you can reinstall it without a bow press. You’ll just need a buddy. I will attach a video (make sure you are very safe while doing it do not let down or fire while they’re putting it in) also make sure that they do not pull on the string to hard while they’re separating it. The peep sight is in your string so that you can create repetition in your shot. I recommend watching a video on how to use them on YouTube. https://youtube.com/shorts/a9oCDDR7d4o?si=ZB20qe4rwmh3B1Rf

Also make sure once you have the peep in the string you slide those two black knots to pinch the peep. This will make sure it does not jump out again
