The Dead Air HUB fixed mount in .578-28 (brand part no. LT305) lets a HUB-compatible suppressor thread directly onto a barrel cut to the .578-28 pattern. Dead Air Silencers makes the HUB insert in many thread pitches, and this is the .578-28 version. HUB compatible means the 1-3/8-24 interface, so it direct threads the Nomad, Primal, Sierra-5, Lazarus-6, Sandman-X and other HUB-compatible silencers. It is a short way to mount by hand, without installing a separate quick-detach mount.
