Oh boy! Do the Russians love their pyros for airsoft. Red Army Airsoft has a video testing  a pre-production versio of a new airsoft mortar that uses the pyros from StraykArt. It looks they can fire the pyro projectivles at distance of 120 metres and they did some rapid launching for the test that also can lead to overheating to the barrel just like the real thing which is not bad for a mortar for airsoft games.
