YHM developed this Q.D. Adapter to convert existing suppressors from other manufacturers to use our much simpler mounting mechanism. This is the same mount design that YHM has been using on our Q.D. suppressors since 2005. Due to its simplistic design, there is virtually no way to incorrectly install the suppressor and risk the chance of it coming loose, yet it provides easy removal.

To install, simply remove your existing mount from your suppressor and thread in our Q.D. adapter. This will allow you to use YHM’s Q.D. flash hiders or muzzle brakes which are sold separately.

  • 17-4PH Heat Treated Material
  • Black Oxide Finish
  • 1-3/8"-24 Thread Pitch
  • Allows the use of YHM Q.D. Mounts to be used with suppressors that utilize 1-3/8"-24 threads.

    Machining is excellent and it fits ( yes they are CNC machined)

    This adapter adds a little length to your suppressor but sometimes it is needed for certain length flash hiders, etc. I recommend a little lithium grease on the threads before installing on the back of the can, since with use it will lock itself tightly to the can (especially if you tighten it securely and you should) to prevent baffle strikes later. (Never-Seez works better but is very messy and is very difficult to get out of your creases of your hands later.) YHM products are superbly machined, burr free and threads well together. I know, since I have a small machine shop (two lathes and two milling machines.)

    Phantom QD Adapter Review

    Posted by Dan_C on Aug 24th 2022

    I picked up the Phantom QD Adapter for my R9 suppressor. The adapter fit the R9 perfectly and allows me to use my Phantom QD muzzle devices with my R9.

    Mounting the suppressor becomes shockingly easy. Line up the threads, twist the suppressor on, and it’s ready to rock!
