Far smaller and lighter than the original Sionics design, but it retains the classic look of the early MAC suppressors by the addition of an over-diameter heat shield, knurled for a steady grip. Not only does this make for a more controllable MAC, the heat shield also makes up the most extraordinary feature of this unit.Â
It doubles as a secure locking device that ratchets back into a rock-solid mount to prevent loosening or dangerous unscrewing during hard use. Initial installation is simple, and subsequent mounting/dismounting is simpler yet - just slide the heat shield forward to disengage the locking mechanism to remove the VIPER from the host firearm.
It is the quietest dedicated suppressor available for one of the most widespread submachine guns ever marketed in the United States. Period. VIPER suppressors are available in .380, 9mm, and .45ACP versions.Â
