Hub Direct Thread Mount 3/4X20
The Dead Air Armament Hub Direct Thread Mount 3/4X20 is a fixed mount insert designed to expand the versatility of your HUB-compatible suppressor. If you're running a Nomad, Primal, or another Dead Air silencer with HUB compatibility, this direct thread adapter lets you mount your can on firearms with 3/4-20 muzzle threads — opening up more rifle platforms without requiring additional muzzle devices or QD systems.
Built from 4140 heat-treated alloy steel and finished in QPQ black nitride, this mount insert is engineered to handle the pressures and vibrations of suppressed shooting while resisting corrosion. The direct thread design means a solid, repeatable connection with no wobble or rattle, and the compact profile keeps your overall setup as trim as possible.
Dead Air's hub-based mounting system is one of the most practical approaches to multi-gun suppressor ownership — buy one can, swap mounts to fit your .308 rifle, your .223, and other firearms with different thread pitches. This 3/4-20 insert fills that need for platforms that use that common large-bore thread standard.

Frequently Asked Questions
What suppressors does this mount work with?
This hub direct thread insert is compatible with any Dead Air suppressor that uses the HUB mounting system, including the Nomad, Primal, and similar models. It accepts the HUB insert standard (1 3/8-24).
Will this work on my rifle with 3/4-20 threads?
Yes — this mount is threaded 3/4-20, the standard large-bore thread pitch found on many .308, .338, and other magnum rifle barrels and muzzle devices.
Is this a permanent mount or can I swap it out?
This is a fixed mount insert. It threads into your suppressor's HUB and stays in place. Dead Air's modular hub system allows you to have multiple inserts in different thread pitches and swap them as needed to match different firearms.
What's included?
You receive the direct thread insert only. Your HUB-compatible suppressor and the firearm with 3/4-20 threads are required for installation.
