Yankee Hill Machine .30 cal Q.D. Flash Hider

This product is currently out of stock and unavailable.


The Yankee Hill Machine (YHM) .30 cal Q.D. Flash Hider is for the Phantom Q.D. and Resonator R2 Sound Suppressors. It retains the excellent flash hiding capabilities of the original Phantom. This flash hider WILL NOT accommodate our 5.56 Phantom®, Phantom® 5.56 M2, or Turbo® Gen 1 Sound Suppressors. Available in a wide array of thread sizes. In 2013 we redesigned our Q.D. Mount and upgraded its style, as well as function:


  • The new Carbon Scrapers (Teeth) removes or scrapes carbon from the internal support system of your can.
  • The Dual Support System supports and aligns the suppressor to your bore
  • Our 5 Port Design decreases visible flash
  • The External Locking Mechanism keeps heat away from the spring mechanism
  • A New High-Temperature Spring holds up better over a longer service life.


  • Aggressive Teeth for a mean aggressive look
  • We removed the External Grooves for a sleek smooth look reduces carbon build-up for easy clean up
  • The Dust Enclosure hides and protects all internal moving parts within the our quick disconnect system.

The devices should be torqued to between 20 and 30 Ft-lbs.
