Dead Air Armament Pyro 2.0 Muzzle Brake W/Da451 Keymicro & .45 Cal Front Cap
Dead Air
The Dead Air DA451 KeyMicro Adapter is a lightweight mounting interface designed for shooters running Dead Air's Ghost-M or Wolfman suppressors on pistols and compact hosts. If you're already invested in Dead Air's suppressor ecosystem, this adapter lets you swap suppressors between KeyMicro and compatible KeyMo muzzle devices without replacing your entire mounting hardware—just unscrew your booster assembly or fixed mount and thread in the adapter in its place.
Built on the same time-tested mounting architecture as Dead Air's full-size KeyMo system, the KeyMicro Adapter scales that proven reliability down to match the footprint and weight budget of modern pistol silencers. At just 3.7 ounces, it adds minimal mass to your setup while maintaining the rigidity and repeatability that serious shooters expect. The adapter works with Dead Air's P-Series socket, the same interface found in the Ghost-M and Wolfman—so compatibility is straightforward if you're already familiar with the system.
Keep in mind that while the KeyMicro Adapter is mechanically compatible with both KeyMicro and KeyMo muzzle devices, actual fitment to a given suppressor depends on the suppressor's internal geometry. Smaller blast chambers optimized for pistol cartridges may have constraints that affect pairing. Dead Air designed this adapter first and foremost to work with KeyMicro muzzle devices, so that's the primary pairing to consider if you're building or expanding a modular pistol suppressor setup.

| Color | Black |
| Weight | 3.7 oz |

| Type | Suppressor mounting adapter |
The adapter is compatible with Dead Air suppressors that use the P-Series socket, including the Ghost-M, Wolfman, and Wolf 9SD. It replaces the booster assembly or fixed mount on those suppressors. Fitment to a specific suppressor depends on internal geometry, so verify compatibility with your model before purchase.
The adapter is mechanically compatible with both KeyMicro and KeyMo muzzle devices. However, Dead Air designed it primarily to pair with KeyMicro muzzle devices, and fitment depends on the specific suppressor's internal chamber and blast configuration.
Simply unscrew your existing booster assembly or fixed mount from the suppressor and thread the KeyMicro Adapter into the same mounting location. It then accepts compatible KeyMicro or KeyMo muzzle devices.
The adapter serves as a mounting interface between your suppressor and muzzle device, allowing you to use your suppressor with different KeyMicro or KeyMo-compatible hosts without replacing the suppressor itself. It's part of Dead Air's modular mounting philosophy for pistol silencers.
