Dead Air Hub Direct Thread Mount M18x1 Fits Sierra 5, Black

HUB Fixed Mount Inserts - 1.375-24 HUB Direct-Thread Interface for Expanded Suppressor CompatibilityHUB fixed mount inserts provide a precision direct-thread interface that expands suppressor compatibility across a wide range of firearms. Machined to industry-standard 1.375-24 HUB dimensions, these inserts thread into compatible suppressor bodies to allow direct mounting to host muzzles without additional hub hardware. Available in multiple thread pitches, the inserts make it simple to move a single HUB-pattern suppressor between hosts while preserving a low-profile, repeatable connection.Built for service, each insert is precision-machined for tight tolerances and reliable engagement with Nomad, Primal, Lazarus 6, Sandman X and other HUB-compatible silencers including Nomad-30 and Primal models. The fixed mount design delivers a solid, low-profile mating surface that minimizes play and overall stack height compared with quick-attach systems, while the choice of thread pitches ensures broad fitment across common muzzle threads.Intended for users who want straightforward direct-thread capability for HUB cans, these inserts improve versatility and simplify logistics for multi-host setups. Confirm correct thread pitch for the host firearm and visually inspect baffle alignment after installation before firing.
