The CGS SCI-SIX is a is a full-size 5.56mm machine gun rated rifle silencer constructed of DMLS (3D-printed) Inconel 718. It exhibits high performance on the MK18 weapon system and is demonstrated to be one of the most balanced high performance designs on the current market, with extreme durability and lighter weight than some legacy designs. The production variant is the result of a multi-tiered third party performance evaluation process in a solicitation that was created by the end-user entity SC IRREGULARS. It is the first CGS production rifle silencer to feature a dedicated muzzle device mount.
