If you need a little more weight on the back of your dart so you can balance out your throw, these Back Balance Champagne Rings for L-style's PRO dart flights are for you. With all the features of the regular plastic and metal Champagne Ring, these add a 0.4-gram piece of tungsten inside. The rings themselves will minimize deflections, hold the flight tighter to the shaft and protect you from those pesky “robin-hood” shots. No more stabbing in between the flight and shaft in the middle of games! Be sure to check out other styles of Champagne Rings including the plastic and premium metal styles.
