Radical Defense CS-5 Compact Suppressor 5.56mm FDE

The Radical Defense CS-5 Compact Suppressor is a hub-mounted design intended for 5.56mm use. It employs a 3D-printed monolithic approach using a nickel-based Super Alloy (Haynes 282) with a Ti6Al4V option noted for semi-auto applications. The forward-venting KFM design controls cyclic rate and helpfully reduces back pressure while providing thermal and flash mitigation. The exterior is finished in a Flat Dark Earth tone with high-temperature protective coatings.
