The PTS MK18 Quick Detach mock suppressor is a faithful replica of a similar silencer that is issued to the US Navy SEALs and other US and international Special Operations Units. Its compact size allows for uncompromised maneuverability without sacrificing its effectiveness. The PTS MK18 QD mock suppressor can be rapidly attached and unattached from a rifle in a combat environment via a unique locking ratchet system when used with the PTS 51T flash hider. Also compatible with the PTS BATTLECOMP 51.0
