VG6 Precision is developing a new muzzle device called the EPSILON 556. This hybrid muzzle brake with some flash suppressing properties will be available some time in December.
The new device has a lot in common with VG6 Precision’s previous muzzle device, the GAMMA 556, including 17-4PH stainless steel construction and a black nitride finish. It also features similar dual blast chambers with side and top ports.
They recently released some videos showing the day light and low light performance of the new device.
