The Dead Air Keymo DA304 Flash Hider M15x1 is a precision-engineered muzzle device built for shooters who run suppressed rifles and want a flash hider that plays well with quality suppressors. Dead Air's design philosophy here is straightforward: eliminate the annoying "ping" that comes from traditional flash hiders by using mass-shifted equal-length tines. This M15x1 model threads onto .30 caliber barrels and works seamlessly with Dead Air's Sandman Series suppressors and other KeyMo-equipped cans, plus it's compatible with KeyMicro-equipped Wolfman suppressors. The engineering matters when you're stacking suppressors and flash hiders—carbon buildup and lock-on can be a real headache during field strips, but Dead Air's design helps prevent that binding.
Built from 4140 HT alloy steel and finished in black nitride, the DA304 weighs 4.00 oz and measures 2.70" in length. It comes with a pre-drilled pin and weld hole at the 6 o'clock position, so if permanent mounting is your plan, you're ready to go. The tine design does the heavy lifting: by balancing the mass and keeping tine lengths equal, the flash hider reduces both muzzle flash and the metallurgical stress that causes ringing and wear over time. That translates to longer component life and less noise signature out the muzzle.
This is the right choice for hunters and precision rifle shooters running a suppressor stack who want a flash hider that's engineered to work with their can rather than against it. Whether you're mounting it for a hunting rifle or a precision bolt gun, the M15x1 threading and KeyMo standard ensure compatibility with a proven suppressor ecosystem.
| Thread Pattern | M15x1 |
| Caliber | .30 caliber |
| Material | 4140 HT alloy steel |
| Finish | Black nitride |
| Weight | 4.00 oz |
| Length | 2.70" |
The DA304 is compatible with Dead Air's Sandman Series suppressors and other KeyMo-equipped cans, as well as KeyMicro-equipped Wolfman suppressors. If you own a different suppressor platform, check its mount type to confirm compatibility.
The DA304 M15x1 is designed for .30 caliber barrels, including full-power rifle cartridges like .308 Winchester, .300 Win Mag, and similar rounds in that bore diameter class.
Yes. The DA304 includes a pre-drilled pin and weld hole at the 6 o'clock position, so if you want permanent installation, the mounting point is already set up.
Dead Air's tine design reduces the stress and binding that typically causes carbon-locking. While no design is 100% immune to carbon buildup, the equal-length mass-shifted tines help suppress the metallurgical issues that lead to stuck mounts, making removal easier during routine cleaning.
