The Irregular Design Group Macro Flow Enhancer in 1/2×28 is a suppressor-dedicated muzzle device for rifles that live suppressed. Irregular Design Group prints the Macro FE in Inconel 718 and uses hollow tine geometry to direct high-pressure gas and unburned propellant toward the suppressor intake. Its design puts gas management and flash reduction first when a compatible suppressor is mounted, instead of balancing suppressed and unsuppressed use. It is the muzzle device half of the Hesion Bow locking system, and this 1/2×28 version is rated for calibers up to 6mm.
