Description
The Yankee Hill Machine YHM-2189-36 is a HUB Direct Thread Mount adapter that converts any 1.375″-24 HUB-compatible suppressor to direct-thread mounting on a 1/2×36 threaded barrel. Machined from heat-treated 17-4 PH stainless steel and finished in Black Oxide, this adapter is built for repeated suppressor mounting cycles.
Designed for .45 caliber host firearms with 1/2×36 muzzle threads, the YHM-2189-36 mates directly with any suppressor built to the industry-standard HUB (1.375″-24) mounting pattern. It adds only 0.3″ of overall length and 1.7 oz of weight to the host platform, with a 1.5625″ outside diameter that stays clear of most handguards and muzzle accessories. As a Yankee Hill Machine component it is Made in the USA to YHM’s quality standards.
To install, thread the YHM-2189-36 directly onto your barrel’s 1/2×36 threads, then attach your HUB suppressor to the 1.375″-24 interface. It is a clean, lightweight solution for running one suppressor across multiple hosts or switching suppressors between platforms without re-threading, and it provides a secure, repeatable lock-up with any HUB-pattern can.
