B&T USA Direct Thread HUB Adapter Features The Direct Thread HUB Adapter is engineered to interface with the 1.375x24 HUB thread pitch on the suppressor side and the standard 5/8x24 muzzle thread on the host side providing a precision-fit mechanical bridge that ensures proper bore alignment and secure lockup during firing. The 5/8x24 thread pitch is the most widely adopted centerfire rifle muzzle thread standard providing broad compatibility across .308 Win 7.62 NATO and other common large-bore rifle host platforms that utilize this standard muzzle thread. The direct thread design prioritizes mechanical simplicity and reliability eliminating the additional components and potential failure points associated with more complex quick-detach mounting systems. The Direct Thread HUB Adapter delivers a clean low-profile mounting solution that keeps overall suppressed system length to a minimum on compatible rifle hosts preserving the balance and handling characteristics that come from a properly proportioned suppressor configuration. B&T USA s established reputation for precision Swiss-influenced manufacturing ensures every component in the B&T USA suppressor accessory lineup meets the dimensional tolerances and quality standards required for reliable long-term performance. For any shooter running a HUB-compatible suppressor on a 5/8x24-threaded centerfire rifle host the Direct Thread HUB Adapter delivers a purpose-built no-compromise mounting solution from a manufacturer with a global reputation for quality.
