Shoot for the stars with the Viper Astro Soft Tip Darts, designed for use with either electronic dart boards or most sisal dart boards. These darts are packed with features starting with the barrel, fashioned from 80% Tungsten and 20% Nickel. Tungsten is a very dense metal, able to create slimmer darts with the same weight as lighter metals; this allows for tighter shot groupings without sacrificing control, increasing your scores. Tungsten is a sign of quality and durability as well because of its density. A higher tungsten content will produce a slimmer dart profile than one with less. More tungsten in the dart increases the price as tungsten is a rare metal and its density takes more effort to machine. The increased price gives a higher quality barrel and can improve performance, increasing scores. Each barrel enjoys knurled bands complimented by diamond-cut etchings, allowing your grip to remain consistent throw after throw. The Astro Darts feature tough, lightweight Aluminum Shafts with diamond cut etchings for a wild look. These shafts feature locking holes that allow a more secure fit to your barrel; you won’t find yourself retightening these shafts after a shot or two. Finally, each dart is finished off with spectacular holographic star graphics graphics adorning each slim flight, for a stellar look. Each set includes six high speed slim flights, twelve extra 2BA Tufflex II Tips, a dart mechanic repair tool, and a TacTech EVA dart case. The TacTech dart case is a great all-in-one case for your new darts. Featuring a hard outer shell and foam lined slots to keep your darts secure, this case has room for everything included in this set!
