The Dead Air HUB Direct Thread Mount in 5/8×24 with SIG taper (brand part no. LT315) attaches HUB-compatible suppressors to 5/8×24-threaded barrels cut with the SIG taper shoulder. Dead Air Silencers machines the mount to the industry-standard HUB (Hybrid Universal Base) interface, and the taper engagement seats the mount squarely against the barrel shoulder for consistent alignment shot after shot. Among Class 3 parts and accessories, this mount favors shooters running SIG-taper barrels who want a light, direct-thread suppressor interface.
