Yhm Hub Direct Thread Mnt M13.5x1lh
The Yankee Hill Machine Hub Direct Thread Mount M13.5x1LH is a precision threaded adapter that converts HUB-compatible suppressors to direct-thread mounting on your barrel. If you've invested in a quality suppressor but want the simplicity and rock-solid return-to-zero of direct threading, this mount bridges that gap—letting you swap mounting systems without buying a new can. It's engineered from 17-4PH stainless steel, heat-treated and finished in black oxide for durability in the field.
Installation is straightforward: remove your existing mount mechanism from the suppressor body, thread this adapter on using a 3/4" open-end wrench, then thread the whole assembly directly onto your barrel's M13.5x1LH threads. The .45-caliber bore handles full-power centerfire rounds without compromise. At just 1.7 ounces, it adds minimal weight to your suppressor system, so you won't notice it affecting handling or balance.
Whether you're setting up a precision rifle for long-range hunting, a tactical build, or simply prefer the direct-thread approach for its simplicity and repeatability, this Yankee Hill adapter gives you the flexibility to run a HUB-mount suppressor without proprietary mounting hardware. It's a practical solution for shooters who want to keep their suppressor system modular and efficient.
