The KAC CRS QDC PRT is a precision muzzle device developed to serve as the mounting interface for Knights Armament QDC suppressors. The design emphasizes consistent alignment and mechanical stability during attachment and removal, supporting repeatable point of impact when used with compatible KAC QDC suppressor assemblies.

The PRT geometry works in conjunction with the QDC locking system to limit rotational movement once a suppressor is mounted. Manufactured from high strength steel and finished for durability, the CRS QDC PRT is intended for hard-use rifle and carbine platforms chambered in 5.56 NATO. No original box or accessories included.
