Practical Muzzle Flash (hack pt2) - VS or With digital?

[@SunilDip]

Without a suppressor can put a tiny led inside the barrel and a small button on trigger?

You could, but with an airsoft handgun it'd be just one LED (so dim enough it'd be unlikely to make much difference) and you'd probably have to get it to vent the gas somewhere else, since the LED would block the inner barrel. These flash units I've been playing with have at least four LEDs, each of which is about the diameter of an airsoft BB.
