The Dead Air HUB fixed mount in 1/2-28 is the insert that lets you direct thread a HUB-compatible suppressor straight onto a 5.56 or rimfire muzzle (Dead Air part no. LT301). It threads into the 1-3/8-24 HUB interface on the back of the can, and the 1/2-28 bore end threads onto your barrel. Dead Air names the Nomad, Primal, Sierra-5, Lazarus-6 and Sandman X among the silencers it fits, along with other HUB-compatible cans. Machined from heat-treated 4140 alloy steel and finished in QPQ black nitride, it is a 0.765-inch insert that weighs 1.84 ounces. It is the simplest, lowest-profile way to run a HUB suppressor without a quick-detach muzzle device.

Key Specifications

• The muzzle thread is 1/2-28, the common pitch for 5.56 and many rimfire and pistol-caliber barrels.
• The suppressor side is the 1-3/8-24 HUB interface, the industry-standard rear mount thread.
• Material is 4140 heat-treated alloy steel, strong enough to hold a can at the muzzle shot after shot.
• The finish is QPQ black nitride, a hard, corrosion-resistant surface treatment.
• Overall length is 0.765 inches, adding little to the length of the suppressor.
• Weight is 1.84 ounces, among the lighter mounts in the Dead Air line.
• It is a fixed direct-thread mount, so the suppressor threads straight onto the barrel without a separate muzzle device.
• Dead Air lists fit with the Nomad, Primal, Sierra-5, Lazarus-6 and Sandman X.
• It also fits other HUB-compatible silencers that use the 1-3/8-24 rear thread.

Frequently Asked Questions

Which suppressors does it fit? Dead Air says it direct threads the Nomad, Primal, Sierra-5, Lazarus-6, Sandman X and other HUB-compatible silencers to your muzzle.

What barrel thread does it need? This version is 1/2-28. Dead Air makes the same HUB fixed mount in other pitches, including 5/8-24, 3/4-24 and .578-28, for other barrels.

Why choose a direct-thread mount over a quick-detach? A fixed mount is short and light, with no separate muzzle device, so the suppressor stays as compact as possible on a dedicated host.
