The Dead Air Xeno muzzle brake is Dead Air’s mount for the Xeno adapter. This muzzle brake comes in two popular thread pitch options: 1/2x28 or 5/8x24. It is also compatible with the Bravo rear thread pitch. It’s also constructed of highly durable nitrided 4140, allowing you to have fun all day at the range, no matter how many rounds you send down range. If you’re looking for a muzzle brake that performs equally as well on a suppressed firearm as well as unsuppressed firearm (why would you do that though?) look no further than the Dead Air Xeno muzzle brake.
