Surefire Hubfa556Bk 5.56Mm 1 3/8"X24 Heat Treated 17-4 Stainless Steel Nitride Black

The SureFire Fast-Attach Hub is a quick-detach adapter that bridges HUB-pattern suppressors to SureFire's SOCOM Fast-Attach muzzle devices. If you've invested in a 1 3/8"-24 threaded suppressor but want to run it on a rifle equipped with a SureFire SOCOM muzzle brake or flash hider, this adapter lets you do exactly that—without tools and without any NFA paperwork. It's the clean solution for shooters who want the speed and reliability of SureFire's Fast-Attach system across multiple suppressors or setups.

The hub is machined from heat-treated 17-4 stainless steel and finished in black nitride, the same materials and process SureFire uses on its combat-proven suppressors. That means it's built to handle the stress of quick-attach cycling and the thermal environment around a muzzle device. Slide it onto your SOCOM adapter, index the alignment slot, and lock it down with the integrated ring—no gunsmith, no hassle. Because it's not a suppressor itself, it's not an NFA item, so it ships and sells without the regulatory delays and paperwork that come with cans.

This is purpose-built for shooters who want flexibility without complexity. Whether you're switching between rifles, testing different suppressors, or consolidating your muzzle-device ecosystem under one fast-attach standard, the SureFire Fast-Attach Hub does one job exceptionally well: it makes your existing HUB suppressors compatible with SOCOM gear.
