Faxon Firearms Direct Thread HUB Adapter Features The Faxon Firearms Direct Thread HUB Adapter is CNC-machined from Grade-5 titanium a material chosen for its strength-to-weight ratio and natural resistance to corrosion under repeated heat cycling. The internal 1/2x28 UNEF thread mates directly to standard 1/2x28 threaded barrels while the external 1.375-24 UNS thread conforms to the HUB mounting standard used by a growing number of suppressor manufacturers. Every adapter is deburred and inspected after machining to ensure a clean repeatable thread engagement that holds zero shift to a minimum when a suppressor is removed and reinstalled. The natural titanium finish requires no coating to resist the elements keeping the part functional even after extended use. This adapter is tested for fit with Faxon s own HARMONIX and CORESYNC suppressors when the correct hub configuration is used giving owners of those cans a direct path to mounting on a 1/2x28 barrel. Because it is designed and manufactured entirely in the USA shooters get consistent quality control from a company with a strong reputation in the barrel and muzzle device market. The lightweight titanium construction adds minimal weight to the muzzle end of a rifle or pistol keeping handling characteristics close to an unsuppressed configuration. For shooters standardizing on the HUB mounting system this adapter is available for sale at GrabAGun.
