Faxon Firearms Direct Thread HUB Adapter Features The Faxon Firearms Direct Thread HUB Adapter is CNC machined from heat treated 17-4 PH stainless steel a material chosen specifically for its combination of strength and corrosion resistance under repeated suppressor mounting and removal. Its M18x1.5 threading is cut to connect directly with metric threaded barrels while the opposite 1.375 inch by 24 thread interfaces with the HUB mounting system used by a range of suppressor manufacturers. Precision machining ensures the adapter threads on with a concentric repeatable fit which keeps the suppressor s bore aligned with the barrel s bore to avoid baffle strikes. This level of fit and finish reflects Faxon s broader reputation for precision barrel and muzzle device manufacturing. A black nitride finish protects the adapter s surface from the heat and fouling that come with suppressed fire while also resisting corrosion from weather and handling over time. The compact adapter design adds minimal length and weight to the overall suppressor setup keeping the system balanced on the rifle. For shooters who already own a HUB compatible suppressor and want to run it on a metric threaded barrel this adapter removes the need for a full new mounting solution. The Faxon Firearms Direct Thread HUB Adapter gives suppressor owners a durable precisely machined way to bridge their mounting system to a wider range of barrels.
