    Hub adapter for R9

    Posted by Ronald Ford on Apr 19th 2026

    My R9 came with the 2/2x28 mount. I had 3 firearms that were threaded 5/8x24. The adapter made it easy to use on all of my firearms.

    YHM R45 End Cap

    Posted by K Tinsley on Dec 28th 2025

    This end cap is perfect as are all of my YHM products. I have the R9 and R45. I run them on several different systems, and the suppressor and adapters work flawlessly. I will be buying more from YHM.
