The Millennium compensator differs from the other .50 Beowulf muzzle brakes in that it produces not only a braking effect, but also a distinct downward force to counteract the muzzle flip of the weapon. The design uses a series of four compound angled slots on each side of the unit to redirect gas in a backward and upward direction. The combined effect of recoil reduction and muzzle jump reduction works very well on the .50 Beowulf and allows for rapid follow up shots. Back blast is noticeable from this unit.
