Radical Defense CS5-FDE Suppressor 5.56 | 1/2×28 | FDE

The Radical Defense CS5-FDE is a compact suppressor designed for 5.56/.223 applications and KFM hub-mounted systems using 1/2×28 threading. The CS-5 employs a monolithic, 3D-printed construction in a nickel-based Super Alloy (Haynes 282) with a high-temperature Cerakote I/R coating in FDE; the manufacturer also references a Ti6Al4V (Ti64) option. The design emphasizes thermal and flash mitigation in a short 5-inch package suitable for carbine-length platforms. Typical applications include precision/range training and competition or field use where compact, durable sound and flash reduction are desired.
