I took my Bow to a shop to have the peap sight put in and so slight adjustments to it. Well the sight was useless I had to buy one from them the sting wouldn't say out of the hole and couldn't get a sraight on look. I had to keep moving my head witch will through off your shot. Therefor I wouldn't have anyone buy this. If you do feel the need to try it go to the store It was almost $2 cheaper there.
