Thread Size:

Bold, aggressive style and awesome performance! This 4 port design has no downward facing ports which helps eliminate dust problems when shooting in the prone position.  The Annihilator Muzzle Brake Maintains the aggressive styling that was so popular with the original Annihilator Flash Hider.

Muzzle device length is 2.225" w/.155" crush washer - 2.38". Length added to barrel is 1.755" (on barrels with 0.6" threads).

  • Threaded 1/2"-28
  • Includes crush washer. 
  • Made from 41L40 Heat Treated Steel RC 26-34.

    Perfect fit, no surprise there being a Yankee Hill product. Excellent machine work, and very nice black finish . And maybe best of all an aptly named wickedly cool way to dress up your rifle !
