Why Choose the Faxon Direct Thread Hub?
This direct-thread hub gives shooters a clean, repeatable HUB interface without the need for additional adapters. Grade-5 titanium offers the best strength-to-weight ratio for reduced front-end weight while preserving concentric alignment and long service life in harsh environments.
Benefits
- Reduced weight: Titanium construction saves ounces at the muzzle for improved balance and handling.
- Precise fit: Industry standard HUB geometry for concentric, low-wobble mounting.
- Corrosion resistance: Titanium resists corrosion and performs reliably in adverse conditions.
- Manufactured in the USA: Machined, inspected, and finished in Cincinnati, Ohio.

FAQ
What barrels is this hub intended for?
This hub is made for barrels with ½×28 internal threads (direct-thread barrels). Confirm barrel thread callouts before installation.
Will this work with my suppressor?
The hub uses industry-standard 1.375-24 UNS (HUB) external threads and is compatible with many HUB-mount suppressors. Confirm your suppressor’s hub part number and configuration for full compatibility.
Does the titanium finish change with use?
Yes — titanium can develop colorization (blue, purple, gold hues) from heat exposure during normal shooting. This oxidation is cosmetic and does not affect strength or function.
Any warranty or compatibility warnings?
Some suppressor manufacturers may not honor their warranty when third-party hubs or adapters are used. Always verify compatibility and warranty terms with your suppressor manufacturer before installation.
Notice: HARMONIX® and CORESYNC® are Faxon Firearms trademarks.
Disclaimer: Confirm fitment and warranty coverage with your suppressor and barrel manufacturers before installation. Titanium color changes from heat are normal and cosmetic only.
