The Dead Air HUB Fixed Mount in 3/4-24 (Dead Air part no. LT303) is the insert that lets a HUB-compatible suppressor direct thread onto a muzzle cut for 3/4-24. One end presents the 3/4-24 host thread to the barrel and the other carries the 1-3/8-24 HUB interface that Dead Air calls HUB compatible. It is machined from 4140 HT alloy steel with a QPQ black nitride finish and measures only 0.765 inch long, so it adds very little to the front of the host. Dead Air lists it for the Nomad, Primal, Sierra-5, Lazarus-6 and Sandman X, along with other HUB-compatible silencers. It is the piece to buy when your muzzle thread is 3/4-24 and you want a fixed, direct-thread setup.
