This combination results in a stunning barrel with innovative, modular protrusions for powerful grip. There are 2 barrel designs, parallel and tapered, each offering grip sequences of varying intensities. Sonic Darts are 90% tungsten, match weighed to +/- 0.5 grams and fitted with clear Supergrip shafts and Sonic flights.
