Desert Tech gives us a brief look at their Quattro 15 Shot Counter Prototype. Should be interesting for those who are mindful of their ammo...

It's fascinating to have shot counters in airsoft guns though you might be more curious on how shot counters work on shotguns, Flatox has a quick demo with one... "Golden Eagle M870 'short' gas replica (airsoft) with integrated OLED shot counter."
