Knight's Armament 5.56 QDC Suppressor

Be the first to review this product



KAC’s line of QDC (Quick Disconnect Coupling) suppressors are currently in service with various SOF and Law Enforcement agencies, and feature an innovative mounting method, providing the user with consistent and minimized POI shift, and effective flash and sound suppression. The attachment method separates the locking parts from mounting surfaces, making carbon build-up a reduced concern. Consistent POI shift is maintained through repetitive lock-up of the mounting hardware during attachment. The QDC line of suppressors is available in two sizes; standard QDC for optimal flash and sound reduction, and shorter CQB for better maneuverability in confined spaces. The QDC line of suppressors are compatible with the KAC QDC muzzle devices, which come standard on all KAC rifles and are also available separately. Please note that the QDC suppressors are caliber specific and can only be used with the corresponding muzzle device.

Muzzle Device is NOT included.
