This muzzle device was developed in response of end users who desired reduced concussion above all other muzzle device performance attributes. This unit features vertical port compensation to assist in muzzle neutrality as well as a gas venturi front aperture to project linear flow of pressure downrange, away from the shooter and nearby friendlies.
