Yankee Hill Machine Co HUB Direct Thread Mount M13.5x1LH – Universal Suppressor Adapter

The YHM HUB Direct Thread Mount provides a standardized connection between YHM suppressors utilizing the HUB interface and firearms with M13.5x1 left-hand threading. This mount allows you to configure your suppressor for direct thread attachment, eliminating the need for a dedicated quick-detach system when a fixed mount is preferred or when shooting with firearms that benefit from the simplicity and weight savings of a direct thread setup.

Installation is straightforward: thread the mount onto your suppressor's HUB rear interface using the included wrench flats, then thread the assembled suppressor onto your threaded barrel. The M13.5x1 left-hand thread pitch is less common than standard 1/2x28 or 5/8x24 threading, so verify your firearm's barrel threading before purchase. Constructed from heat-treated steel with a durable finish to withstand the thermal and mechanical stresses of suppressor use.
