The Faxon Titanium Direct Thread to Hub Adapter in 1/2×28 is a lightweight suppressor mounting solution that combines extreme weight savings with precision engineering. Faxon Firearms CNC machines it from aerospace grade titanium to deliver a durable, corrosion resistant suppressor interface that does not add meaningful weight to the muzzle. It allows you to mount any 1.375×24 TPI HUB compatible suppressor onto a 1/2×28 threaded barrel. That makes it ideal for .223 Wylde, .223 Remington, and 5.56 NATO AR-15 builds where lightweight performance matters.
Weight at the muzzle is the most expensive weight on a rifle. Every ounce out there costs you more in handling than an ounce anywhere else.
What the Faxon Titanium Direct Thread Adapter Solves
HUB is the industry standard mounting thread that lets a single suppressor work across many different mounting systems. This adapter is the direct thread option in that ecosystem, converting a common 1/2×28 barrel thread into a HUB interface with the fewest possible parts and the least possible weight.
Direct thread mounting is also the most concentric option available, since there are no locking collars or ratchet mechanisms between the barrel and the can. Fewer interfaces mean fewer opportunities for misalignment.
It suits precision AR-15 builders, lightweight rifle enthusiasts, and high round count shooters who want a suppressor interface that will not distort under sustained fire.
Key Features
- CNC machined from aerospace grade titanium for extreme weight savings
- Converts a 1/2×28 threaded barrel to a 1.375×24 TPI HUB compatible interface
- Maintains perfect concentricity between the barrel and the suppressor
- Corrosion and heat distortion resistant even under sustained fire
- Suited to .223 Wylde, .223 Remington, and 5.56 NATO AR-15 builds
- Simple direct thread design with no additional locking hardware to fail
Materials and Specifications That Matter
Titanium is the entire argument for this part. It offers an exceptional strength to weight ratio, so the Faxon Titanium Direct Thread to Hub Adapter adds a fraction of the mass a steel adapter would while handling the same heat and pressure. Titanium also resists corrosion naturally, which matters on a component that lives in the gas stream.
Heat distortion resistance is the specification that separates a good adapter from a poor one. A part that warps under sustained fire destroys the alignment between bore and suppressor, and a baffle strike is an expensive way to learn that lesson. Precision machining keeps the concentricity consistent and the accuracy repeatable.
Installation, Alignment, and Care
Clear the rifle, remove any existing muzzle device, and thread the adapter onto the clean 1/2×28 barrel threads. Follow the manufacturer’s torque guidance and verify alignment before firing, ideally with an alignment rod through the suppressor. Never skip that verification step on a new mounting setup.
Because titanium can gall against steel under heat, use an appropriate anti seize or high temperature lubricant on the threads as the manufacturer directs. That single habit prevents the adapter from seizing to the barrel after a hot session.
Direct thread mounting means the suppressor threads onto the adapter itself, so check tightness between strings of fire. A can that backs off under vibration will shift point of impact and eventually risk contact with the bullet path.
Inspect the threads periodically, clean carbon from the shoulder, and confirm the adapter is still torqued correctly before each range trip. Suppressor ownership is regulated, so confirm your state and local law before purchasing any related components. Our parts and upgrades collection carries barrels, muzzle devices, and other build components.
Light, precise, and built from the right material for the job, the Faxon Titanium Direct Thread to Hub Adapter is the sensible way to bring a HUB suppressor onto a standard threaded barrel. Thread it on and go quiet. Ships direct to your door, no FFL required.
