The Quick Detach Coupler (QDC) line of Sound Suppressors and Muzzle Devices are proprietary items designed for secure interoperability.  The coupling device itself consists of multiple ball bearings arrayed in a circular pattern which fit into sockets specifically machined into various muzzle devices to accept the QDC.  The bearings are aligned with the sockets by way of a V-shaped notch that seats the device onto an index pin.

Designed with Phantom styling in mind but works as a muzzle brake and compensator. This 4 port design has no downward facing port which helps eliminate dust problems when shooting in the prone position. The 5.56mm Slant Comp/Brake is threaded 1/2-28 and includes a crush washer.
