Dead Air
The Dead Air KeyMo Flash Hider for SCAR 17 is a suppressor-ready muzzle device engineered for shooters running Dead Air's modular suppressor ecosystem. This DA305 model threads 5/8-24 to fit the SCAR 17 platform and features Dead Air's signature equal-length tine design that eliminates the metallic "ping" common to traditional flash hiders. Built from 4140 HT alloy steel with a hard black nitride finish, it's a rugged, low-profile component that pairs seamlessly with Sandman Series suppressors or other KeyMo-compatible silencers.
What sets the KeyMo platform apart is its quick-disconnect reliability. The suppressor removes cleanly without carbon-locking onto the mount—a real quality-of-life improvement if you shoot suppressed regularly and need to swap cans or perform maintenance. The flash hider arrives pre-drilled at the 6 o'clock position, ready for pin-and-weld installation if you're building a permanently attached setup. At 4 ounces and 2.70 inches in length, it adds minimal profile to your rifle while maintaining the thermal and flash signature control you need in low-light or tactical scenarios.
This is a purpose-built part for SCAR 16/17 owners already committed to the Dead Air suppressor lineup or considering the jump to modular, field-serviceable silencer design. It's not a standalone flash hider; it's a mounting interface that assumes you'll run suppressed. If that's your plan, the KeyMo system justifies its investment through repeatability and ease of use.
| Model | DA305 |
| Thread Pattern | 5/8-24 (SCAR 17) |
| Bore Diameter | .30 caliber |
| Material | 4140 HT Alloy Steel |
| Finish | Black Nitride |
| Length | 2.70" |
| Weight | 4.00 oz |
| Mount Type | KeyMo Quick-Disconnect |
Yes. The DA305 is threaded 5/8-24, which is the standard SCAR 17 muzzle thread. Verify your rifle's thread pitch before purchase to ensure compatibility.
The Dead Air KeyMo flash hider is compatible with Dead Air's Sandman Series suppressors and other KeyMo-equipped cans. It is also compatible with KeyMicro-equipped models like the Wolfman. Confirm your suppressor model has a KeyMo or KeyMicro mount before buying.
The flash hider arrives pre-drilled with a pin-and-weld hole at the 6 o'clock position. You will need to source the pin and install it according to local law and your preferred setup. If you plan temporary installation without pin-welding, you may use it as a standalone muzzle device, but the KeyMo system is optimized for suppressor use.
The KeyMo quick-disconnect design allows your suppressor to remove cleanly without carbon-locking to the flash hider—a major convenience factor if you run suppressed frequently. This modularity makes field maintenance and suppressor swaps much easier than fixed or threaded-only mounts.
