Description
The Viper mounts securely on the unmodified Mac 10, 11, 12 9mm Ingram submachine gun barrels with a unique mount that prevents unintentional loosening or unscrewing during use. Initial installation is simple, and subsequent installation and removal simply involves sliding the suppressor handguard forward to disengage the locking mechanism.
Although smaller than sionics design, the Viper significantly outperforms the original while maintaining the classic appearance. In addition to being a part of the locking mechanism, the rear four inches is an oversized heat shield, knurled for a cool, positive grip.It is one of the quietest dedicated suppressors available for the most popular submachine gun ever marketed in the USA.
