YHM’s line of sRx® products were designed with aesthetics and ease-of-use as the top priorities. The YHM® sRx® (Suppressor Rx) System will be the obvious choice for anyone looking for a sleek, low-profile, suppressor set up-that’s also built to withstand rigorous use. This is our prescription for the shooter who cares about the aesthetics of their build as well as its ease-of-use. (Photo: YHM-4400 sRx Q.D Adapter)

At the heart of the sRx® program, is the sRx® Q.D. Adapter. This low profile Q.D. Adapter/Mounting Interface attaches to industry standard HUB compatible1-3/8” x 24 threads. It features an internal taper seal in front of the threads that locks your suppressor on and forms a tight seal to contain gases while in use. This means no gases or debris can build up on the threads.

Some of the exciting benefits of the YHM sRx System:

  • TIMELESS. (No need to shim/time to barrel)
  • Small/low profile
  • No moving parts
  • Large taper in front of the threads allows consistent mounting
  • Lighter than many Q.D. mounting offerings on the market
  • Can be permanently attached to firearm barrel if needed
  • Finish: Black Oxide
  • Made in USA

As always, all YHM® Products are covered by our Lifetime Manufacturers Warranty--more information HERE.

    SRX

    Very satisfied with this attachment so far. SRX has been a great system for me. Suppressor locks down tight, and seemed to stay pretty tight for the duration of my last trip to the range.

    At first I order the wrong adapter. I was given a refund and got the right one. Great place to get what you need or want.
