M3 Heavy Metal steel tip darts are 90% tungsten and have extremely slim barrels with shark rills. M3 barrels have an external thread for attaching shafts and tips. Instead of screwing the tips or shafts inside the barrels, they are screwed onto the external M3 threads. With 17-25% more mass the volume of the dart is shifted outwards without having a decrease in weight, and the dart is remarkably slimmer. The equally distributed mass results in a more balanced dart. The decreased air resistance results in earlier flight stabilization and improved flight dynamics. The thinner profile allows for tighter groupings and improved scoring. Comes complete with M3 shafts, flights, and steel tip points.
