Qdc Flash Suppressor Kit 22 Cal 1/2-28 Steel Black

The Knights Armament QDC Flash Suppressor Kit in .22 caliber is a steel quick-disconnect mounting platform designed to pair with KAC QDC sound suppressors—but stands on its own as a capable flash hider even without a suppressor attached. If you run a suppressor-ready .22 rifle and want the flexibility to swap between canned and uncanned shooting, or simply need a reliable flash-hiding muzzle device for your rimfire, this is worth a serious look. The machined steel construction and matte black finish deliver the durability and low-profile aesthetics KAC is known for.

On its own, the QDC Flash Suppressor effectively diffuses blast and reduces flash signature—useful for low-light range sessions or hunting when you want to minimize muzzle signature without committing to a suppressor. The 1/2-28 thread pitch is a common standard for rimfire platforms. Installation is supported by a 7-piece shim kit and Rocksett adhesive included in the box, giving you the tools to achieve a solid, repeatable fit on your muzzle.

The real value proposition is modularity: keep this flash hider on your rifle, then simply quick-disconnect a KAC suppressor when you want to add sound reduction. It's a smart choice if your shooting needs span both canned and uncanned scenarios, or if you're building a .22 platform that may run a suppressor down the road.
