Most Helpful Positive Review Good product with one issue
Every Dead Air muzzle device I have ever purchased has been of excellent quality and craftsmanship. This one was no exception, well built, well finished, overall an excellent flash hider, with one minor exception. Unfortunately this particular issue is inherent in the nature of the specific device. Because this is designed for the Sig angled barrel taper, it cannot be timed. Although timing is not critical for a flash hider, I like for all of my suppressor host guns to have their muzzle devices time to the same so that the suppressor goes on the same way on each gun, always at 12:00.

Dead Air KeyMicro

by Robert Padgett, Verified Owner from MD, United States Written on March 31, 2026
Solid, heavy duty and built to last. This is one of the best flash hiders you can buy. I have 6 of these on different guns. Dead Air suppressors with the Keymo hub fitment fit perfect. Suppressor slides right on with a couple turns, locks onto the suppressor. Well worth the money

Perfect addition for my Mpx

by Joshua Wyatt, Verified Owner from VA, United States Written on November 15, 2025
The only concern I had when purchasing my Mpx was the reviews I had seen saying that it was difficult to suppress, and that the thread pitch on the barrel made it difficult to find a muzzle device that could be used with a suppressor without spacers or throwing the bore alignment off. This muzzle break took all the worry out, as it threaded right on to my barrel. Now I can use my suppressor with no worries.

Great mount

by Nathan K., Verified Owner from AL, United States Written on July 5, 2025
This is a high quality mount for your can. I would recommend this for a person who wants ease of removal. And if you have multiple hosts for said can. Easy on, easy off. Is slightly on the heavy side.
Pros:
  • Easy removal/installation
Cons:
  • Heavish
Best Used for:
  • anything
Would recommend: Yes
