95% Tungsten Barrels have a slim profile, allowing for tighter grouping of shots which increase scoring. Precision machined barrels are the most aerodynamic design, for maximum flight velocity. Heavy duty 100 micron flights are among the hardiest flights in the industry, standing up to punishing throws. Aluminum Shafts feature locking holes, the most secure way to fasten shafts to barrels and improve stability. Includes six flights, three extra nylon replacement shafts, and Dart mechanic repair tool.
