The Dead Air CT5P 5/8×24 black suppressor is the CT5P Patrol threaded 5/8×24 for direct attachment, built for 5.56 NATO and 6mm ARC duty rifles (Dead Air part no. CT5PDTBLK5824). Dead Air calls the CT5P its first patrol-specific silencer: gas-regulated, ultralight and low in backpressure. It builds on lessons from the Lazarus 6 and Sandman X, and removing the HUB interface brings it to 5.49 inches and 13.7 ounces in direct-thread form. Dead Air says it reduces muzzle flash and spark to near undetectable levels on 5.56 NATO barrels as short as 10.5 inches. For a rifle or muzzle device already threaded 5/8×24, this version mounts without an adapter.
