The .44 revolver I fired (Ruger Super Redhawk), made surprisingly little flash. My Rock River AR15 with the hybrid comp/hider (standard A3 IIRC?), in low light and night time shooting made next to no visible flashes except for every now and then. My friend's AK47 made a bit of flash but it was not every shot, more like every fifth you'd get a little flash. And my 870 didn't make much at all if any.
I think what folks don't understand is there's a reason modern powder is called "smokeless". Go read the wikipedia article about it, just look up smokeless powder, it's a very good article. And I agree with what several have said, and I can tell you AS a handloader....there's a difference in powders used for civillian ammunition vs military. And, note too that milspec rounds are typically loaded hotter than their civillian counterparts.
The footage Booster posted I think is a perfect example. You DO INDEED see muzzle flashes....just not every shot fired...and not typically a brilliant ball but a quick flash of flame. As I understand it, it chances of flash increase with shots fired between cleanings.
