My bow was dead on 4 days ago,when I was shooting out of my stand.The next day me and dad shoot(wind is blowing)we are both shooting to the right so I say well its just the wind.So I shoot yesterday and it does it again without wind so I try to ajust my sites.Well as I am undoing the allen screw I strip it so I have to get new sites.What kind should I get I need help![]
