The DAIR KeyMicro Flash Hider M13.5x1LH is a compact muzzle device built for shooters who want effective flash signature reduction without bulk or weight. Designed to work standalone or paired with the KeyMicro Adapter, this flash hider brings the proven technology behind Dickinson Arms' industry-respected KeyMo system to a minimalist platform. It's engineered for rifles and carbines where a slim profile and lightweight construction matter—whether you're hunting, running drills at the range, or building a purpose-built upper.
The KeyMicro Flash Hider features a 9mm bore and uses the M13.5x1 left-hand (LH) thread profile, making it a direct fit for compatible uppers. On its own, it delivers straightforward flash reduction; combine it with the KeyMicro Adapter to unlock additional mounting flexibility and expanded accessory options. If you're already invested in the KeyMo ecosystem, this device is also compatible with the KeyMo Adapter, so you're not locked into a single platform as your setup evolves.
What makes the KeyMicro line compelling is the philosophy behind it: precision engineering without unnecessary complexity. Dickinson Arms stripped away the excess to create a flash hider that does its job efficiently and integrates cleanly into modern short-barreled platforms or any build where barrel real estate is at a premium. Whether you're a hunter running a compact setup or a shooter optimizing a precision build, this is a no-nonsense muzzle device that earns its spot on the end of your barrel.
