The Dead Air HUB Fixed Mount in 1/2×28 (Dead Air part no. LT301) is a simple, reliable way to direct thread a HUB suppressor onto a barrel with a 1/2×28 muzzle thread. The suppressor side uses the 1.375×24 HUB interface, so it works with HUB-compatible suppressors, and the barrel side threads straight onto the muzzle with no muzzle device needed. Without a quick-detach system it gives a rock-solid connection and minimal point-of-impact shift. The insert is 4140 heat-treated alloy steel in a QPQ black nitride finish. This Dead Air mount suits a dedicated suppressor host that will not be switching muzzle devices.
