SEAR

I'm into heavy weapons. 60 mm M2 mortar I'm starting right now, but I have a weakness for 20 mm Flak gun. It would be much more expensive project though.

Hi all, I have experience with anti-tank guns and similar weapon systems firing powder-filled projectiles at flat trajectory. Sadly, such weapons are no go on airsoft due to general absence of full-face masks. How about mortars on similar tech? Their projectiles are falling right from above and be gentle enough to not to hurt even in case of accidental hit. Is this something that could be accepted here and there? I make strictly non-pyro stuff. The powder fill is mainly to highlight the impact point and enable virtual kill radius to be applied.
