YHM, in cooperation with Sound Technologies, is proud to bring you the Phantom .338 Sound Suppression System. The proven performance of YHM's Phantom Flash Hider reduces muzzle flash while the Sound Technologies baffle design (U.S. Patent #7,073,426) reduces muzzle noise by up to -28 dB. The fast attach design allows you to permanently install the Phantom Flash Hider or Muzzle Brake and then install the Sound Suppressor without the use of tools when sound suppression is desired. Our Phantom Q.D. Mount System holds the sound suppressor firmly in place by hand tightening and allows the sound suppressor to be removed by hand when no longer needed. A gas seal keeps the threads clean so the suppressor will not bind, making removal a breeze. The Phantom Q.D. Mount supports the sound suppressor in two places making misalignment nearly impossible, even if the sound suppressor is not fully tightened.

Warranty:

YHM offers a lifetime warranty against defects in material and workmanship and will repair or replace, free of charge, any sound suppressor manufactured by YHM. The Phantom Flash Hider must be installed by a licensed gunsmith or the warranty will be considered null and void. Use of an aftermarket mounting system will result in the warranty being considered null and void. This warranty does not cover damage to the sound suppressor and/or host firearm resulting in whole or in part from criminal or negligent use, improper or careless handling, modifications, defective, improper hand-loaded, or reloaded ammunition, or neglect. This warranty does not cover damage to the sound suppressor or host firearm due to improper installation of the Flash Hider, the Sound Suppressor, or an improperly threaded barrel. The minimum barrel length for which the suppressor is warranted is 16 inches. Any repairs not covered by this warranty will be charged to the owner.
“I finally got to use my Phantom Sound Suppressor over the weekend.  I have it on an IMI Lone Eagle .308 single shot pistol.  I worked up some subsonic loads consisting of 220 gr. round nose at 1020 fps.  I was absolutely blown away by the almost total lack of noise.  I heard a small “puff” then I heard the ping of the bullet when it hit the metal target 100 yds away.  To give you an exact description of the sound... it sounded like someone opened up a shook up soda can... matter of fact I think the soda can would probably be louder. I will recommend YHM to anyone who asks me about suppressors.”
