Huxwrx HUB Direct Thread Adapter (Bravo 1.375x24mm) - 1/2x28 TPI Precision Fit

The Huxwrx HUB Direct Thread Adapter in 1.375x24mm with 1/2x28 TPI threads is a precision mounting solution for shooters running fixed barrel systems with direct-thread suppressors. Built from 17-4 stainless steel and finished with black nitride for durability and corrosion resistance, this adapter allows you to thread a suppressor directly onto your barrel without relying on muzzle brakes or other intermediate devices. It's purpose-built for shooters who want a clean, compact setup on a locked-breech platform.

This adapter is designed to work with Huxwrx HUB suppressors and maintains compatibility across the RAD 9 and RAD 45 platforms, giving you flexibility if you're running multiple calibers or expanding your suppressor lineup. The wrench flats make installation and removal straightforward—no special tools or guesswork required. Because this is a direct-thread mount, keep in mind it's engineered exclusively for fixed barrel systems; it is not suitable for unlocking or reciprocating barrels, where the cycling action can cause damage to both the adapter and suppressor.

Heat-treated and finished to withstand consistent use, this adapter delivers the kind of precision fit and corrosion resistance you'd expect from a professional-grade component. If you're building a suppressed rifle or pistol platform and want a streamlined, repeatable mounting interface, the Huxwrx HUB Direct Thread Adapter is a solid choice.
