If you've already invested in a SilencerCo Omega suppressor with an ASR QD mount but want to run it on a rifle built around a Dead Air Armament muzzle brake or flash hider, the Dead Air Key-Mo Mount Adapter bridges that gap. This adapter lets you swap out your existing ASR mount and attach your Omega to Dead Air's platform without buying a whole new suppressor. It's a practical solution for shooters who want flexibility across multiple rifle builds without redundant gear.
The Key-Mo mounting system is built for convenience. You get true one-hand-on, one-hand-off attachment—no tools needed, no staking required on the muzzle device. That means faster mounting and dismounting in the field or at the range, plus easier cleaning and maintenance when you need to separate suppressor from rifle. The adapter also lets you tuck a suppressor under a hand rail if your build calls for a compact setup, something that matters for AR-15s and other modern rifles where space is tight.
Dead Air's Key-Mo ecosystem has become a go-to standard for shooters who value simplicity and reliability. If you're already running a SilencerCo Omega on one rifle, this adapter opens the door to using it on other platforms without the cost or hassle of buying a second can. It's the kind of unglamorous accessory that actually saves time and money over the long haul.

What muzzle devices does this adapter work with?
The adapter mounts to Dead Air Armament muzzle brakes and flash hiders that use the Key-Mo platform.
