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.
