Intimidate your opponents and dominate your dart games with the Viper Underground Steel Tip Darts designed for use with sisal dart boards. These darts are packed with features starting with the barrel, fashioned from Tungsteel-brass alloy. Constructing the darts in this fashion allows us to bring you tough, weighted barrels without breaking the bank. The highest end darts have a unique appearance from the tungsten from which they are fashioned. Tungsteel plated brass gives you the high end appearance and durability similar to tungsten at a lower cost. We use this alloy to provide the highest quality barrels at the best cost to you. Each front-weighted barrel enjoys grip-enhancing grooves, allowing your hand placement to remain consistent throw after throw. The Underground Darts feature tough, lightweight aluminum shafts. These shafts feature locking holes that allow a more secure fit to your barrel; you wonﾒt find yourself retightening these shafts after a shot or two. Finally, each dart is finished off with your choice of four different terrifying Underground designs adorning each flight, for a sensational look on each dart. Each set includes six wide glide flights, three extra nylon shafts, and dart mechanic repair tool.
