Matching the thread is the whole job here: the Yankee Hill Machine HUB Direct Thread Mount in M13.5×1 left-hand turns a HUB compatible suppressor into a direct thread unit for a M13.5×1 left-hand barrel (Yankee Hill Machine part no. YHM-2189-M). It replaces the suppressor’s existing mount mechanism, goes on with a 3/4-inch open end wrench, and then the suppressor threads onto the barrel. Machined in the USA from 17-4 PH stainless steel with a black oxide finish, it is a simple way to move one suppressor between hosts.

Key Specifications

• The thread size is M13.5×1 left-hand, the barrel thread this version is cut to match.
• The suppressor side is the 1.375-24 HUB interface, so it works with HUB compatible suppressors.
• It converts the suppressor to direct thread mounting, replacing the existing mount mechanism.
• The diameter is 1.5625 inches, matching the HUB suppressor body.
• The length is .3-inch, so it adds very little to the suppressor.
• The material is 17-4 PH stainless steel, strong enough to carry a suppressor.
• The finish is black oxide, which resists corrosion and glare.
• Installation uses a 3/4-inch open end wrench, a common tool most shooters already own.
• It is made in the USA by Yankee Hill Machine.
