KNIGHTS ARMAMENT COMPANY 

5.56MM CRS-3 QDC PRT SUPPRESSOR 

The Knight’s Armament QDC 5.56 CRS-3 is designed to maximize sound and flash suppression on 5.56 platforms. The CRS-3 is a slightly lighter evolution of the CRS-1 while offering improved sound suppression, and it connects directly to compatible KAC 5.56 QDC flash hiders.

This kit includes a KAC 5.56 QDC Flash Hider (PN 30555), providing the compatible muzzle device needed to complete the setup. Available in Black or FDE, the CRS-3 delivers the proven QDC mounting system and signature reduction expected from Knight’s Armament.
