Aggressive Design and Excellent Flash Reduction

In the midst of combat, the importance of a good flash hider can’t be overstated.  What you want is something that controls the rise of the muzzle, while effectively reducing the flash, ensuring you have a clear line of sight to your target for a follow-up shot.  The AT3 Combat Flash Hider does both of those, with a 4-port design that diverts propellant gases leaving the barrel, while providing compensation to control the barrel’s natural whip.  It also looks great, with aggressive styling and a tough phosphate finish that will stand the tests of time and use.  This Flash Hider also comes with a crush washer to make timing it onto your AR15 barrel simple.


  • Reduces muzzle flash – critical in night-shooting scenarios
  • Aggressive “teeth” provide hand-to-hand combat benefits
  • Machined from tool steel with a phosphate coating
  • For use on 5.56mm/.223 Rem rifles with 1/2-28 threads
  • Includes crush washer
  • 1/2 X 28 thread pattern (standard AR-15 .225/5.56 barrels)
  • Backed by the Lifetime AT3 Warranty
