Surefire Fast Attach Hub 5.56 3/8-24

The Surefire Fast Attach Hub 5.56 3/8-24 is a quick-detach adapter that lets you run 1 3/8-24 thread-pattern HUB suppressors on Surefire SOCOM Fast-Attach muzzle devices without the complexity of suppressor registration. This is a non-NFA component—it's the mount itself, not a regulated silencer—so it's available without the paperwork and wait times that come with owning an actual suppressor. If you've already invested in quality HUB suppressors and want the speed and convenience of Surefire's proven Fast-Attach system, this hub converts that investment into a true quick-detach setup.

The Fast-Attach Hub mimics Surefire's own suppressor mounting interface, engineered to the same exacting dimensions and tolerances as their combat-tested back sections. Attachment and removal happen in seconds with no tools required—just slide the hub over the muzzle device, index it on the built-in slot, and tighten the lock ring. The result is the same rock-solid, repeatable zero you'd get from a factory Surefire suppressor mount. It's machined from heat-treated stainless steel and finished in black nitride/DLC coating, which means it'll handle hard use and corrosion with the durability you expect from Surefire's reputation.

Made in the U.S.A., this hub is compact and relatively light, so it won't add significant weight or length to your rifle's muzzle. Serious shooters running suppressed rifles on the range or in the field appreciate Fast-Attach mounts because they let you swap cans or remove a suppressor entirely without breaking zero or fussing with tools. If a HUB suppressor is already part of your battery, this hub makes it a lot more practical.

Frequently Asked Questions

What suppressors does the Fast Attach Hub work with?

The Fast Attach Hub converts any 1 3/8-24 thread-pattern HUB suppressor for use with Surefire SOCOM Fast-Attach muzzle devices. Note that you'll need the Z-72636 Spanner Tool for proper mounting of HUB suppressors to this hub.

Is this hub itself regulated as a suppressor?

No. The Fast Attach Hub is a non-NFA component—it's a mounting adapter only. You can own and use it without any suppressor registration or tax stamp. It's available wherever Surefire products are sold without suppressor-related restrictions.

Do I need tools to attach or remove the hub from my muzzle device?

No. The Fast-Attach design lets you slide the hub over a Surefire SOCOM muzzle device, index it on the built-in slot, and secure it with the lock ring—all without any tools. Removal is equally quick.

What's the difference between this and mounting a suppressor directly?

The Fast Attach Hub lets you use HUB-pattern suppressors with the speed and convenience of Surefire's Fast-Attach mounting system. It's engineered to the same tight dimensions as Surefire's factory suppressor back sections, so you get the same repeatable fit and zero every time you attach or remove it.
