Fletcher Rifle Works ST-174-HUB-PB HUB Mount Taper Adapter - Plan B

The Fletcher Rifle Works ST-174-HUB-PB is a precision HUB mount taper adapter purpose-built to bridge HUB-pattern suppressors and Plan B compatible muzzle devices. Machined by Fletcher Rifle Works in Carrollton, Texas, this adapter provides a clean, repeatable interface for mounting a Plan B tapered muzzle device to a HUB-equipped suppressor without re-threading or shimming the host.

As the -PB variant in Fletcher's ST-174 HUB adapter family, the HUB side carries the industry-standard 1.375x24 HUB thread that mates to a HUB-spec suppressor, while the output side presents a precision Plan B taper shoulder that locks concentrically with Plan B muzzle brakes and mounts. The result is a solid, aligned lockup that holds up shot after shot, and a black finish that blends with most host setups.

Use the ST-174-HUB-PB to step up a Plan B muzzle brake to a HUB suppressor, or to build a versatile can setup that swaps cleanly between muzzle devices on a single suppressor. Pair it with other Fletcher Rifle Works ST-174 HUB adapters and muzzle accessories for a complete, modular suppressor-mounting system.
