Fletcher Rifle Works HUB Direct Thread Adapter Features The Fletcher Rifle Works HUB Direct Thread Adapter is machined from titanium giving it the strength to handle repeated mounting and dismounting cycles without adding unnecessary weight to the end of a barrel. At only 1.2 oz the adapter keeps the muzzle balance close to what it was before a suppressor was added which matters for shooters who care about handling and swing. Its 1/2x28 thread pattern matches a wide range of rimfire and 5.56 caliber barrels making it a versatile piece for anyone standardizing their guns around the HUB mounting system. The compact 2 length and 1.5 diameter keep the footprint tight so it does not interfere with other muzzle devices or handguard clearance. Because the adapter is purpose-built for the HUB quick-attach system it allows a suppressor to be moved quickly between host firearms without re-threading or re-indexing each time. This speeds up switching a suppressor between a rifle and a pistol caliber carbine or between multiple rifles sharing the same thread pitch. Titanium construction resists corrosion and heat better than many alloy steel alternatives extending the adapter s service life under sustained suppressed fire. For shooters building out a modular suppressor setup this direct thread adapter is a straightforward durable piece of the puzzle available for sale at GrabAGun.
