YHM's Sound Suppressor Covers with an industry leading suppressor cover retention system. Using our unique locking straps your cover is secured to your suppressor ensuring it stays in place while shooting. Most other covers will loosen up over time and begin to slide off. When you are on target the last thing you need is to look up at your cover.
These covers are made from only the highest quality materials. The base layer is flash rated to 3000°F and the middle material is rated to 1800°F. The outer shell is a durable 1000 Denier Cordura Nylon that is water resistant and stands up against fading abrasion rot and mildew. We even chose a high quality fire resistant thread to ensure every aspect of the cover can stand up to the toughest environments.

  • Outer Shell constructed of 1000 Denier Cordura Nylon
  • Interior sleeve rated to 3000°F and will not slip or shift on your suppressor.
  • 4.5 inches in length
  • Will fit Turbo K Resonator K and R9 YHM Suppressors

If the suppressor is kept at temperature for an extended time the heat starts to dissipate through the first two layers and will eventually bring the temperature of the Cordura shell above it's rated temperature. This would take an extreme amount of firing but it can be done. Where we have seen issues in the past is with 5.56/.223 rifles that have barrel lengths under 14″. The amount of heat generated in the suppressor itself can quickly get the temperatures above their rated levels.

YHM designed this sRx Blast Deflector to work with all sRx muzzle devices. The Blast Deflector attaches to the mount just like a YHM Suppressor.

Specification:

  • Material: 4140 Chrome Moly steel
  • Length: 2.2”
  • Width: 1.03”
  • Weight: 4.7oz.
  • Finish: Black oxide
  • Made in the USA.

YHM’s line of sRx products were designed with aesthetics and ease-of-use as the top priorities and that is no different for the YHM sRx Flash Hider (YHM-4405's). This Q.D Flash Hider comes in two variations (1/2 x 28" & 5/8 x 24") and it's compatible Q.D. Adapter/Mounting Interface attaches to the industry standard (HUB) 1-3/8” 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 gasses while in-use. This means no gasses or debris can build up on the threads.

The sRx Flash Hider adds minimal length and weight to the suppressor set up while also allowing you to reap all the benefits of the new YHM sRx System-when used in conjunction with The sRx Adapter. The full YHM sRx (Suppressor Rx) System will be the obvious choice for someone 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.

Muzzle device length is 2.3". Length added to barrel is 1.675" (on barrels with 0.6" threads).

Some of the exciting new benefits of the YHM sRx System are as follows:

  • TIMELESS. (No need to shim/time to barrel)
  • Small/low profile
  • No moving parts
  • Large taper in front of the threads allows for consistent mounting.
  • Lighter than many Q.D. mounting offerings on the market
  • Can be permanently attached to firearm barrel needed
  • Length: 2.300"
  • Diameter: .9375"
  • Material: 4140 Steel
  • Finish: Black Phosphate
  • Caliber(s): 9mm (.390 diameter) or smaller
  • Thread Size: sRx

The YHM sRx System-just what the doctor ordered!
