The Dead Air HUB Fixed Mount in 3/4-20 (Dead Air part no. LT306) is a direct thread insert that lets a HUB-compatible suppressor thread straight onto a barrel cut to the 3/4-20 muzzle thread. HUB compatible means the 1 3/8-24 interface, so this is the part you need to direct thread a Nomad, Primal, Sierra-5, Lazarus-6, Sandman X or another HUB silencer to your muzzle. Dead Air offers the insert in a range of thread pitches, and this one is the 3/4-20 version. It is machined from 4140 heat-treated alloy steel and finished in QPQ black nitride. At 2.78 ounces it is the heaviest pitch in the HUB fixed mount list.
