The ML37 is a versatile, easy-to-use signaling device, from which all commercially available 37mm signal cartridges can be fired. This is the same launcher the Austrian military uses, just switched out to 37mm tube so it dosn’t have to be registered as a destructive device per the ATF!

The signaling device is made from high-quality materials such as hard-anodized, forged aircraft-grade aluminum 7075 T6, and thus guarantees its function and the highest level of corrosion protection even in common climate zones.

The slim lightweight design allows for storage and transport in the tightest of spaces.

This launcher is not a firearm and an “FFL” is not required.

Launcher can be shipped straight to your door.

This launcher is for signaling purposes only!!!
