Faxon Firearms Plan B to HUB Adapter Titanium 1.375-24

The Faxon Firearms Plan B to HUB Adapter is a precision suppressor mounting accessory that bridges the gap between Faxon's MuzzLok Plan B muzzle device interface and the industry-standard HUB (Hub Classification) pattern. This lets you mount any HUB-compatible suppressor on a firearm equipped with a Faxon Plan B device, opening up a huge range of suppressor options for your host rifle or pistol.

Machined from Grade-5 Titanium (Ti-6Al-4V), this adapter delivers an excellent strength-to-weight ratio with outstanding corrosion resistance. Titanium's natural properties make it ideal for repeated mount and unmount cycles without galling, thread damage, or excessive wear. The result is a lightweight, durable interface that holds up to hard use in the field and at the range.

The adapter features precision-machined 1.375-24 UNS-2A threads on the primary suppressor interface, providing a rock-solid, repeatable lock-up with any standard HUB-compatible suppressor. A secondary 29-32-24 UNEF-2B thread pattern is also machined in, supporting additional configurations such as Harmonix and Coresync muzzle devices, adding versatility for shooters running those specific systems.

Designed and manufactured in the USA, the Faxon Plan B to HUB Adapter is built to exacting tolerances for a precise fit and consistent return to zero. Whether you are swapping suppressors between hosts or setting up a dedicated suppressor on a Plan B-equipped rifle, this adapter delivers a reliable, repeatable interface every time you mount it.
