The Dead Air Silencers RXD R-Series Flash Hider Front Cap for 5.56 (brand part no. RXD206) is a replacement front end cap sized for 5.56 NATO bore diameter, used on Dead Air’s RXD R-Series flash hider muzzle device. As a wear or upgrade component, the cap can be swapped without replacing the entire muzzle device, letting owners re-caliber an existing R-Series unit or replace a worn part. It’s machined to the same tolerances as the rest of the RXD line for a secure, consistent fit. It ships as a standalone component.
