ML 2" mortar
We just finished a prototype of light mortar heavily inspired the British WW2 piece. It runs on compressed air thus several dimensions needed to be adjusted. It is non-pyrotechnical and mortar bombs are filled with magenta marking powder to highlight impact points. Effective range is around 110 meters. It was designed for paintball mainly with a focus on quick deployment and destruction of important point targets. But it could work for some WW2 airsoft events as well.

Prototyping is over. Here is a firing demonstration.
