The Faxon Titanium Plan to Hub Adapter bridges Plan B style suppressor mounts with 1.375×24 TPI HUB standard suppressors in a high strength, ultra lightweight package. Precision machined from aerospace grade titanium and finished in QPQ nitride, it offers the exact fit and durability Faxon Firearms is known for while cutting weight out of the system for better balance. If you own a Plan B mount and a HUB can, this is the part that connects them.
Suppressor mounting standards have multiplied faster than anyone’s parts drawer can keep up with. Adapters are how you avoid buying the same can twice.
What the Faxon Titanium Plan to Hub Adapter Does
The job is conversion, and the requirement is precision. This adapter takes a Plan B style interface and presents the 1.375×24 TPI HUB thread that most modern suppressors and mounting systems now use, so a can built around the HUB standard can ride on a host set up for Plan B.
It suits AR-10, AR-15, and precision rifle shooters who run more than one host or more than one mount type. It is especially valuable to anyone building a lightweight rifle, since the weight it saves sits at the very end of the barrel where mass has the largest effect on how the gun handles.
Key Features of the Faxon Titanium Plan to Hub Adapter
Titanium and tight tolerances are the whole story here.
- Converts Plan B style mounts to the 1.375×24 TPI HUB suppressor standard
- Precision machined from aerospace grade titanium for extreme strength at low weight
- QPQ nitride finish for surface hardness and corrosion resistance
- CNC machined to extreme tolerances for perfect concentricity between interfaces
- Repeatable suppressor alignment with minimal point of impact shift
- Suitable for AR-10, AR-15, and precision rifle platforms
Weight is the reason most shooters buy the Faxon Titanium Plan to Hub Adapter over a steel equivalent. Every ounce removed from the muzzle reduces the leverage acting against your support arm, which shows up as a rifle that tracks flatter and holds steadier off a bipod.
Materials, Concentricity, and Heat
Concentricity is the specification that matters most in a suppressor adapter. Any misalignment between the mount and the can multiplies down the length of the suppressor, and the consequences range from a shifting point of impact to a baffle strike. CNC machining to extreme tolerances is what guarantees that the Plan B and HUB interfaces share a common axis.
Titanium is the right alloy for the job. It offers an exceptional strength to weight ratio and outstanding heat resistance, so the adapter maintains its integrity under sustained fire and extreme conditions without adding the mass a steel part would. On a rifle where you are already carrying a suppressor, that weight savings is felt immediately.
The QPQ nitride finish adds a hard, corrosion resistant surface layer on top of the titanium. That helps the adapter shrug off the carbon and heat cycling that live at the muzzle. Faxon Firearms applies the same finish across its muzzle device line.
Practical Use, Installation, and Care
Install with an unloaded, verified clear rifle and clean threads on both interfaces. Degrease everything, check for burrs, and hand thread before applying any tool so you never cross thread a titanium part. Torque to the manufacturer’s specification rather than by feel.
Verify alignment before you shoot suppressed. An alignment rod is inexpensive and takes thirty seconds to use, and it is the difference between a good day and an expensive one. Confirm your zero after adding or removing the suppressor and log the shift so you can predict it later.
Clean carbon buildup off the threads periodically with a nylon brush and a carbon solvent, taking care not to use aggressive abrasives on the nitride surface. Anti seize designed for high heat applications makes future removal far easier. Browse muzzle devices, mounts, and rifle components in our parts and upgrades collection.
Light, precise, and built to hold alignment shot after shot, this adapter solves a real compatibility problem without adding weight where you least want it. Ships direct to your door, no FFL required.
