Description
Direct thread mounting is fine until you own more than one rifle. That is where the IWI HUB-T QD Adapter SS earns its keep. This stainless steel adapter threads into the 1.375×24 HUB rear mount on your suppressor and converts it to IWI's quick detach interface, letting the can snap on and off any host wearing one of IWI's IWS QD flash hiders or muzzle brakes. Set up a QD muzzle device on each rifle, and one suppressor covers the whole safe.
How the HUB-T QD Adapter Fits Into IWI's IWS System
IWI built its IWS suppressor line around the HUB+ mounting system, an upgraded take on the familiar HUB thread pattern that adds a taper for tighter, more consistent lockup between mount and can. This adapter is the QD half of that ecosystem. Install it once, torque it down, and swapping the suppressor between hosts becomes a seconds-long job instead of a wrench-and-timing exercise. Because the rear thread is the industry standard 1.375×24, the adapter is at home in HUB-compatible suppressors beyond IWI's own lineup as well. One thing worth knowing before you order: it is not compatible with the IWS22 rimfire suppressor, so this one is for your centerfire cans.
Built From Stainless Steel for Muzzle-End Abuse
The muzzle end of a rifle is a rough neighborhood, with heat, carbon, and pressure hammering everything near the blast. That is why IWI machined this adapter from stainless steel with a black finish rather than going for the lightest possible option. It is a part designed to be installed and forgotten, holding alignment shot after shot so your point of impact stays consistent every time the can goes back on.
Who Should Grab the IWI HUB-T QD Adapter SS
If you are running an IWS suppressor, or any HUB-threaded can, across multiple rifles, this adapter plus a QD muzzle device on each host is the cleanest way to do it. It keeps the suppressor secure under recoil, makes hot swaps painless at the range, and ties neatly into IWI's mount-and-muzzle-device lineup. Simple part, big convenience.

Frequently Asked Questions
Will the IWI HUB-T QD Adapter work with suppressors from other brands?
Yes, as long as the suppressor uses the industry standard HUB rear thread pattern, which is 1.375×24. That covers a huge range of modern centerfire cans from most major manufacturers. The adapter threads into the rear mount just like any other HUB accessory.
Do I need a specific muzzle device to use this adapter?
You do. The HUB-T QD Adapter is designed to lock onto IWI's IWS QD flash hiders and muzzle brakes, so you will want one of those on each rifle you plan to run the suppressor on. It is not cross-compatible with QD muzzle devices from other brands, since each company uses its own locking interface.
Can I use the HUB-T QD Adapter with the IWS22 rimfire suppressor?
No, IWI specifically notes this adapter does not work with the IWS22 rimfire can. It is intended for the centerfire IWS suppressors and other HUB-threaded suppressors. If you are running the rimfire model, stick with its dedicated mounting options.
What is the advantage of a QD setup over direct thread mounting?
Speed and repeatability. With a QD muzzle device on each rifle, you can move one suppressor between hosts in seconds without spinning the whole can on and off hot threads. A good QD interface also resists loosening under recoil and returns to the same position each time, which helps keep your point of impact consistent.
