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.

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
