Yankee Hill Machine .30 cal Q.D. Muzzle Brake


: $94.25 ($14.25)



For users who desire a muzzle brake instead of a flash hider, Yankee Hill Machine (YHM) now offers this Q.D. Mount muzzle brake for our Light Tactical .30 Cal. Sound Suppression Systems. Sound suppressors naturally work as a muzzle brake, this Q.D. mount will decrease recoil of your host firearm even more.

This muzzle brake WILL NOT accommodate our 5.56 Phantom, Phantom 5.56 M2, or Turbo Gen 1 Sound Suppressors.

Shim Kit is included in the price.

Our Redesign of the YHM-5M2-QD has a smooth sleek look which eases cleaning, and because of popularity we decided to apply this to our .30 Cal. Muzzle Brakes.  The redesign also features an improved mounting service which makes attachment quicker, and easier.

Three thread sizes are available:

  • 5/8″-24 (YHM-4302-MB-24A, Price includes SHIM-3302-SET)
  • 1/2″-36 (YHM-4302-MB-36A, Price includes SHIM-3102-SET)
  • 1/2″-28 (YHM-4302-MB-28A, Price includes SHIM-3102-SET)

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