Description
Sometimes the simplest mounting setup is the best one. The HUXWRX HUB Direct Thread Adapter takes any suppressor built on the industry-standard HUB pattern (1.375×24) and lets you thread it straight onto a 5/8×24 barrel. No proprietary muzzle device to buy, no extra lockup hardware to fuss with. Just spin it on, torque it down, and get to shooting. The 5/8×24 thread pitch covers a huge swath of rifles, including most .308 Winchester, 6.5 Creedmoor, .300 Blackout, and AR-10 pattern barrels, plus plenty of threaded bolt guns and lever actions.
Built From 17-4PH Stainless, Not Cutting Corners
HUXWRX machines this adapter from heat-treated 17-4PH stainless steel and finishes it in black nitride, so it shrugs off carbon, heat, and repeated install-and-remove cycles without the threads wearing loose. That matters on a part that lives at the muzzle and takes a beating every range trip. The precision-cut threads give you consistent alignment shot after shot, which is exactly what you want between your bore and your baffle stack.
Where the HUB Direct Thread Adapter Fits In
Because HUB has become the common language for big-bore rifle cans, this adapter plays nice with suppressors from a long list of manufacturers, not just the HUXWRX lineup. If you run cans across multiple rifles, keeping a direct thread adapter on each host makes swapping quick and painless. One thing worth knowing before you order: this adapter is made for fixed-barrel firearms. Tilting-barrel handguns need a piston or booster assembly instead, so keep this one on your rifles, carbines, and other fixed-barrel hosts.
For a lot of folks, direct thread is still the cleanest way to hang a suppressor. It keeps overall length down, cuts out extra weight at the muzzle, and removes one more potential point of looseness from the system. This little chunk of stainless does one job and does it right.

Frequently Asked Questions
Will the HUXWRX HUB Direct Thread Adapter work with suppressors from other brands?
Yes. The outer 1.375×24 thread is the industry-standard HUB pattern, so this adapter works with any suppressor built on the HUB standard, not just HUXWRX cans. Plenty of popular rifle suppressors from other manufacturers use HUB mounting. Just confirm your specific can is HUB-compatible before ordering.
What rifles use 5/8×24 barrel threads?
The 5/8×24 pitch is the standard for most .30 caliber and 6.5mm rifles, including .308 Winchester, 6.5 Creedmoor, .300 Blackout, and 7.62 NATO barrels. You will also find it on most AR-10 pattern rifles and many threaded bolt actions and lever guns. Double-check your barrel threading before you buy, since some barrels in these calibers do come threaded differently.
Can I use this HUB adapter on my pistol?
No, this adapter is designed for fixed-barrel firearms only. Tilting-barrel handguns, which covers most semi-auto pistols, need a piston or booster assembly to cycle reliably and avoid damaging the suppressor. Keep this one on rifles, carbines, and other fixed-barrel hosts.
How do I install the HUXWRX direct thread adapter?
Thread the adapter onto your clean, 5/8×24 muzzle threads by hand until it seats, then snug it to the manufacturer's torque spec with an appropriate wrench. From there, your HUB suppressor threads onto the 1.375×24 side. Check it for tightness periodically during shooting sessions, as with any direct thread setup.
