I've been trying to figure out what this weapon was and I can't find it. And do they make a civilian version. At the time, I was in the field with some Brit Special Forces near the Iraq/Turkey border. It was small, I think 5.56, had the magazine behind the trigger, it was green, and had optics (1.5 or maybe 2x magnification at the most). Really interesting little weapon. Anybody got a clue?
