Most Helpful Positive Review Great flash reduction!
I have this on a bcm 11.5 5.56 ar pistol and it works very well at reducing muzzle flash. I am planning on getting a sandman s suppressor some time in the future which this will work with. Its also a good looking muzzle device.

Flash hider vs brake

by Danno, from TX, United States Written on May 2, 2025
I prefer these over the muzzle brake, as they are far more desirable to be around when shooting if you aren’t running your can.

Dead Air For sure

by Jackie Barton, Verified Owner from AL, United States Written on January 20, 2025
I am quite impressed with Dead Air products. I own several flash hiders and muzzle brakes for my rifles, and Dead Air was the first quick-detach system I encountered, which has made a positive impression on me. I highly recommend their products for anyone looking to suppress their rifle. Their easy quick-detach system is intuitive and efficient. Additionally, both the flash hiders and muzzle brakes are expertly crafted, making them essential components for any firearm enthusiast.

Awesome Flash hider

by Nick, Verified Owner from AL, United States Written on April 6, 2021
This is a must have if you have a pistol or SBR and are looking to run a dead air suppressor. I'm not a fan of the brakes since they produce way too much concussion when not suppressed, especially with the shorter barrels. This is well designed, robust and looks cool. The only negative I can think of is the last two times I ordered this flash hider from OP, there were no shims in the pack. Luckily I had some spares laying around.
Pros:
  • Function
  • Looks
Cons:
  • None
Best Used for:
  • competition
  • Self defense
Would recommend: Yes

Great flash hider

by Ryan J, Verified Owner from WY, United States Written on April 17, 2020
Dead Air Armament makes the best muzzle devices in the game. The keymo system works incredibly well and the devices themselves function as they should without a suppressor. I thought it was better than my old AAC flash hider
Best Used for:
  • Suppressors
