Peep sight use

[steelheadSABO]

So I had an old bow given to me it's a Pearson spoiler plus 70lb draw at 30". The one thing I can't figure out is the sight, it's a copper john dead nuts 2 with 4 pins and looks like any other sight i've seen except on the string where the little donut peep sight usually is there is a green plastic thing instead with no hole in it?? How do I go about using this sight. I'm totally new to archery if you cant tell haha.

Maybe it's a kisser button meant to go to the corner of your mouth as an anchor point? I would still recommend getting a peep installed.

Take it in to Big Game Archery in abby and get Wayne to check it over and make sure the draw length is right for you. and install a peep.
