The Knights Armament QDC Flash Suppressor Kit in 30 Cal 5/8"X24 gives you a dual-purpose muzzle device that works hard whether you're running it standalone or pairing it with a KAC QDC sound suppressor. Built as a quick-disconnect mounting platform, this steel flash hider minimizes muzzle flash and blast signature—critical when you need to stay off thermal or avoid giving away your position. The matte black finish handles hard use without fuss, and machined construction means it'll hold zero and take abuse without wearing out.

If you're already invested in the KAC suppressor ecosystem or planning to build around it, this QDC flash suppressor makes the transition seamless. Swap suppressors or run bare in seconds, and you're not losing capability when you do. For shooters who value reliability and modularity over one-trick solutions, this is the platform to build on.

Installation comes with everything you need: a 7-piece shim kit to dial in a perfect fit on your barrel and Rocksett adhesive to lock it in place. The shims let you tune concentricity, which matters for accuracy and suppressor performance down the road.
