Dead Air DA311 KeyMo Flash Hider Black Nitride 4140 HT Alloy Steel M13x1LH Threads 2.70" OAL 22 Cal
$75.00
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.

Frequently Asked Questions
Is the DA311 KeyMo flash hider compatible with my Dead Air suppressor?
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.
Can I permanently install this flash hider?
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.
What makes this flash hider different from standard designs?
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.
What thread pitch does this fit?
The DA311 is threaded M13x1LH—left-hand—and designed for .22 caliber rifles with that specific thread pattern.
