The Dead Air DA311 KeyMo flash hider is a rugged muzzle device engineered for .22 caliber rifles that demand reliable suppressor compatibility and proven flash management. Built from 4140 HT alloy steel with a durable black nitride finish, this flash hider accepts M13x1LH threads and mounts directly onto Dead Air's suppressor ecosystem via the industry-standard KeyMo interface. Whether you're running the Sandman Series, KeyMicro-equipped Wolfman, or another KeyMo-compatible suppressor, this hider delivers the rigid, repeatable mounting your precision setup requires.
Dead Air engineered this flash hider with a distinctive equal-length tine design that shifts mass strategically to eliminate the metallic "ping" common to traditional designs. That means cleaner reports downrange and a mounting system that won't carbon-lock to your suppressor during removal—a genuine quality-of-life improvement for anyone who rotates gear or runs multiple hosts. The 2.70-inch overall length keeps your rifle's ergonomics balanced, and the pre-drilled pin and weld hole at the 6 o'clock position is ready for permanent installations if you're building a fixed setup.
This is a serious piece of precision hardware, not a gimmick. If you're suppressing a .22 rifle and want dead-reliable suppressor mounting without the hassle of stuck connections or performance compromises, the DA311 KeyMo flash hider belongs on your short list.
| Model | DA311 |
| Caliber | .22 |
| Thread Pattern | M13x1LH |
| Overall Length | 2.70 inches |
| Material | 4140 HT Alloy Steel |
| Finish | Black Nitride |
| Weight | 4.08 oz |

The DA311 works with all Dead Air suppressors featuring KeyMo mounts, including the Sandman Series and KeyMicro-equipped Wolfman. If your suppressor has KeyMo, this hider is your direct interface to it.
Yes. The DA311 includes a pre-drilled pin and weld hole at the 6 o'clock position, so you can have a gunsmith permanently secure it to your barrel if desired. KeyMo quick-detach is the default, but permanent mounting is an option.
The equal-length tine design shifts mass to eliminate the metallic "ping" that typical flash hiders produce, and it won't carbon-lock to your suppressor, meaning tool-free removal and reattachment every time.
The DA311 is threaded M13x1LH—left-hand—and designed for .22 caliber rifles with that specific thread pattern.
