Radical Defense CS3TI Carbine Suppressor — .300 Blackout

The Radical Defense CS3TI (CS-3 Ti) is a titanium carbine suppressor engineered for .300 AAC Blackout with a 5/8×24 thread and included flash hider. The unit uses a 3D-printed monolithic Ti6Al4V alloy construction and a forward-venting design to manage cyclic rate while assist ports reduce back pressure. The exterior is treated with an IR non-reflective Cerakote for thermal and visual signature reduction.

Manufacturer literature describes the CS-3 series as highly durable and capable of sustained full-automatic fire; that capability is stated by the manufacturer and is reflected in the product’s design and materials.
