Dead Air Armament Pyro 2.0 Muzzle Brake W/Da457 Xeno & .45 Cal Front Cap

The Dead Air Armament Pyro 2.0 muzzle brake is a modular recoil management system built around Dead Air's KeyMo ecosystem. If you're running a suppressor-ready rifle but want the flat-shooting control of a dedicated brake instead of a flash hider, the Pyro 2.0 bolts on in seconds over your existing KeyMo muzzle device—no gunsmithing, no tool swaps. This package ships complete with the KeyMo adapter, the all-new Pyro vented shroud, and a .45 caliber P-Series front cap, so you're ready to shoot out of the box.

What makes the Pyro 2.0 genuinely useful is its modular design. The shroud uses Dead Air's HUB compatibility standard, which means it also accepts the DA457 Xeno adapter—letting you migrate between KeyMo and Xeno muzzle devices without buying a new brake body. The .45 cal front cap is swappable with other P-Series caps, so you can tailor the setup to your barrel diameter if your needs change. It's the kind of thoughtful engineering that appeals to shooters who want versatility without redesigning their whole setup every time they build a new gun.

This is a brake-first tool: if you're chasing minimal muzzle flash for signature control, a traditional flash hider remains the better choice. But if you want recoil reduction and don't mind the flash signature, the Pyro 2.0 delivers on efficiency and simplicity. It's a smart fit for precision rifle builds, short-barrel rifles where muzzle jump is real, and anyone already invested in the KeyMo or Xeno ecosystems and looking to consolidate their muzzle device strategy.

Frequently Asked Questions

Is the Pyro 2.0 compatible with both KeyMo and Xeno muzzle devices?

The Pyro 2.0 ships with the KeyMo adapter and mounts directly over KeyMo devices. The shroud is HUB compatible and accepts the DA457 Xeno adapter separately, allowing you to use it with Xeno muzzle devices as well. You'll need to acquire the Xeno adapter as a separate purchase if you want that compatibility.

What's included in this package?

This package includes the Pyro 2.0 muzzle brake, the KeyMo adapter, the all-new Pyro vented shroud, and a .45 caliber P-Series front cap. All the pieces you need to install and run are in the box.

Can I swap the front cap for a different caliber?

Yes. The .45 cal P-Series front cap included is interchangeable with other P-Series front caps, so you can change it if your rifle's barrel diameter differs from .45 caliber or if you later need a different size.

How fast is installation?

The Pyro 2.0 installs in seconds over your existing KeyMo muzzle device. No gunsmithing or additional tools are required—it's designed to be a simple, quick swap.
