Flash hider / exit gas concentrator "Nov Mini" - Black
This is a replica of barrel's flue gas concentrator, device designed for special forces to be used explicitly in CQB scenarios. Regular silencers and muzzle brakes disperse flue gases on sides in order to compensate rifle's recoil. In this case, gases are lead in shot's direction, rather than to sides. It is made on purpose to prevent burns / concussion of other nearby operators.
