Dead Air
The Dead Air Armament KeyMo GOV Flash Hider in 5/8-24 thread is a purpose-built muzzle device engineered for shooters who run suppressors and demand rock-solid reliability. Built on Dead Air's KeyMo GOV platform—a quick-detach system developed for professional duty use—this flash hider pairs precision engineering with real-world durability to keep your rifle running hard whether you're shooting suppressed or planning to swap cans in the field.
Constructed from nitride-coated 17-4 stainless steel, the KeyMo GOV Flash Hider is built to handle sustained firing, corrosive environments, and the thermal stress that comes with repeated suppressor use. The nitride finish resists erosion and wear, protecting both the hider itself and your barrel threads over thousands of rounds. When you run this hider with a KeyMo GOV HUB Adapter, you get access to Dead Air's secondary retention system—a mechanical backup that locks the suppressor in place beyond the basic quick-detach action, giving you confidence under extreme conditions and heavy use.
The mounting system itself is fast: just one-half to two-thirds of a rotation locks your suppressor down, so you can swap cans without tools and without fuss. At 4 ounces and 2.7 inches long, the profile stays compact while delivering the durability that separates professional-grade gear from everything else. This is a hider designed for shooters who won't tolerate compromise—whether you're at the range, in the field, or running a rifle that demands dependability.
| Thread Pattern | 5/8-24 |
| Caliber | .30 caliber |
| Material | 17-4 Stainless Steel |
| Finish | Black Nitride |
| Length | 2.70 inches |
| Weight | 4.00 oz |
The KeyMo GOV Flash Hider works with any suppressor equipped with a KeyMo GOV-compatible mount or adapter. For the full benefit of the secondary retention feature, pair it with a suppressor that accepts the KeyMo GOV HUB Adapter.
No, the KeyMo GOV Flash Hider is the muzzle device only. It threads onto your barrel and serves as the quick-detach interface for compatible suppressors sold separately.
The 5/8-24 thread pattern is common on .30 caliber rifles, particularly modern AR-10 platforms and larger bolt guns. Verify your barrel's thread pitch and diameter before purchasing.
This is primarily a suppressor mounting interface. Flash reduction performance depends on the specific suppressor used with the hider; consult Dead Air's suppressor specifications for flash reduction data.
