The Dead Air HUB Direct Thread Mount in .578-28 (brand part no. LT305) is a fixed mounting insert that threads your HUB-compatible suppressor straight onto a .578-28 muzzle, the standard threading on .45-caliber pistol hosts. Dead Air Silencers machines the mount from heat-treated 4140 alloy steel with a black nitride finish, and the industry-standard HUB interface (1-3/8×24) carries it across the Nomad, Primal, and the broad field of HUB-compatible silencers. Among Class 3 parts and accessories, this mount favors shooters running a suppressor on a .578-28-threaded .45 host.
