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:
- Length added to Suppressor: .600”
- Weight: 1.88 oz.
- Diameter: 1.563”
- Material: 17-4 PH Stainless Steel
- Finish: Black Oxide
- 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
- Made in USA
As always, all YHM® Products are covered by our Lifetime Manufacturers Warranty–more information HERE.

SRX
Posted by Thomas Breeze on Aug 18th 2025
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.

sRx QD adapter

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.
