MAXTACT Hades and Fury Barrel kits.
It is the first barrel with adjustable rifling to increase or diminish the pressure going through the barrel on the fly.
This works with a barrel inlet with rods that can be adjusted through a ring on the barrel.
The Fury has a straight rifling while the Hades comes with a 1/8 turn rifling to give the ball a spin.
