Fine tune your game to your exact specifications with the Viper Bobcat 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 a nickel plated alloy. Constructing the darts in this fashion allows us to bring you tough, weighted barrels without breaking the bank. Nickel plating is a method that has been used in construction for its high end appearance and durability at a lower cost. We use this alloy to provide the highest quality barrels at the best costs to you. The included Add-A-Gram system is a unique way to bring versatility to your dart sets. Each dart can be adjusted from 16 to 19 grams. Each barrel enjoys knurled bands and hand painted rings, allowing your grip to remain consistent throw after throw. The Bobcat Darts feature tough, lightweight Aluminum Shafts. 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 bold bobcat designs adorning each flight, for a daring look. Each set includes three extra flights, three extra nylon shafts, six extra 2BA Tufflex II Tips, dart mechanic repair tool, three flight protectors and a Deluxe Dart Pal Case with graphics matching your darts. The Deluxe Dart Pal Case is a great all-in-one solution for your new darts. Featuring a hard outer shell and cloth lined slots to keep your dart secure, the Deluxe Dart Pal has room for everything included in this set!
