Buck Magnet is correct about the Stealth stab there's 2 hole's on this stab one on the front and one on the back ,if you find that your bow roll's forward a little too fast or far to what your liking's,you can turn it around and put the screw on the front and this will lesson the forward roll .But also by having the heavy end in you will also increase your dampening of any excess vibration's coming from your riser,if it's needed.
As for the question of where you can buy the Stealth ,there are some store's that do sell them ,but I can't remember off the top of my head which one's.You can go to
www.stealtharchery.com and Jerry will get one off to you just as quick as you can order it. It's definately the best stab that I've ever used ,and I'm sure you'll find the same .
