IWI HUB-T Direct Thread Adapter Features The IWI HUB-T Direct Thread Adapter builds on the widely recognized 1.375x24 HUB rear thread pattern by adding a taper surface that increases engagement between the mount and the suppressor. This added surface contact results in a more rigid secure attachment at the muzzle improving both consistency and accuracy when the suppressor is installed. Machined from stainless steel the adapter is built to handle repeated mounting and removal without wearing down critical threads. Its 5/8x24 thread pattern makes it compatible with a wide range of common rifle and pistol barrel threads. Because the HUB-T system is reverse compatible with earlier HUB-pattern mounts existing IWI suppressor owners can upgrade their adapter without needing to replace their entire suppressor system. The direct thread design keeps the installation straightforward threading directly onto a properly threaded barrel without additional tools. A black finish matches typical firearm hardware keeping the overall setup low profile. For shooters running IWI silencers or other HUB-compatible suppressor systems the IWI HUB-T Direct Thread Adapter is available for sale at GrabAGun.
