Important Notes

  • Heat Coloration: Titanium will naturally oxidize and change color when exposed to heat, developing blue, purple, or gold hues. This is a normal and cosmetic effect that does not affect performance or durability.
  • Warranty Notice: Some suppressor manufacturers may not cover their warranty when third-party mounts or adapters are used. Always check with your suppressor manufacturer before installation.

Notice: HARMONIX® and CORESYNC® are Faxon Firearms brands.
Disclaimer: Always confirm thread fit and compatibility before installation. Titanium heat discoloration is normal and purely cosmetic.
