The Pyro 2.0 converts KeyMo flash hiders into a high-performance muzzle brake by fitting a vented shroud over an existing KeyMo muzzle device. Precision-machined components mate quickly and securely to reduce recoil and muzzle rise for flatter rapid fire, while retaining the low-flash performance of the underlying device when the shroud is removed. The kit includes a KeyMo adapter and vented Pyro shroud, both also available separately. Installation is fast and tool-simple, allowing users to switch between low-flash and brake configurations in seconds. The HUB-compatible Pyro shroud also accepts Xeno adapters, enabling compatibility with the Xeno quick-attach ecosystem. Compact and serviceable, the Pyro 2.0 offers an easy way to add braking performance to KeyMo-based setups without permanently altering the host muzzle device.
