Five Stone Tactical B Drive HUB Adapter - Heat Treated
The Five Stone Tactical B Drive HUB Adapter with a Heat Treated finish is a Plan B-compatible suppressor adapter that connects a suppressor with the common 1.375x24 Bravo, or HUB, rear thread to compatible right-hand Plan B muzzle devices. It gives shooters a specialized mounting component for standardizing a HUB-equipped suppressor around a compact Plan B-type interface.
This Heat Treated configuration is precision-machined from 17-4 PH H900 stainless steel and weighs 2.2 oz. Integrated 1-1/4-inch wrench flats provide a positive tool surface for installation and removal without relying on the exterior of the suppressor body.
Build a clean Plan B-to-HUB connection. Confirm the suppressor's rear thread and muzzle-device interface, then select the matching Five Stone Tactical B Drive configuration at BattleHawk Armory.
1.375x24 Bravo HUB Suppressor Interface
The B Drive uses the widely adopted 1.375x24 Bravo thread to install into compatible HUB-equipped suppressors. That interface allows the suppressor to receive the B Drive adapter while the adapter's muzzle-device side engages compatible right-hand Plan B devices. This configuration is intended for shooters who want a straightforward, low-complexity mounting path without changing the suppressor itself.
Plan B Right-Hand Muzzle Device Compatibility
The muzzle-device side is designed for compatible Plan B right-hand interfaces. Plan B describes the mounting pattern, not universal firearm or suppressor fit. Before installation, confirm the exact suppressor HUB thread, the muzzle device's thread direction and geometry, available blast-baffle clearance, and any minimum engagement requirements for the complete system.
17-4 PH H900 Stainless Construction
The adapter is machined from 17-4 PH H900 stainless steel, a robust material suited to the heat and mechanical loading present in a suppressor mount. The Heat Treated exterior distinguishes this SKU while maintaining the same core B Drive geometry and function as the alternate finish.
Integrated Wrench Flats and 2.2 oz Weight
Integrated 1-1/4-inch wrench flats provide controlled tool engagement during installation and removal. At 2.2 oz, the adapter adds limited mass to the back of the suppressor while providing the required HUB-to-Plan-B interface. Use the correct wrench and follow the current installation procedure for the suppressor and muzzle device.
Installation and Fitment
Work only on an unloaded, cool firearm and suppressor. Clean the mating threads, inspect for damage, and confirm that no shoulder, taper, or blast-baffle interference is present. Apply appropriate anti-seize or thread treatment only where directed, tighten with the proper tool, and verify bore alignment before live fire. A qualified gunsmith should perform the installation when fitment or alignment is uncertain.
