The Radical Defense CS-3Ti black suppressor is a compact 7.62mm can set up for .300 Blackout (Radical Defense part no. CS3Ti). It mounts through a hub interface and comes with a KFM flash hider threaded 5/8×24. The black finish suits a standard black rifle, and the compact body keeps a short .300 Blackout build easy to handle.
