Little boys playing with guns ?
Guns are dangerous things and are responsible for a great deal of unnecessary death and suffering, they need to be controlled and kept out of the hands of criminals and children. But most of the commenters talking above about the technicalities of AK's etc are obviously for the most part ex service men and not little boys with a hard on for blued steel, those that aren't appear to be sufficiently well informed to be worth listening to. Most anti gun types are N.I.M.B.Y types who when the shit hits the fan will always ask why the government and the army isn't doing something about it but the rest of the time will happily condemn all the people in the armed forces as savages and look down on them from their lofty intellectual perches.It's an unfortunate fact that a fundamental part of the human condition involves sometimes killing people who don't agree with us and untill we evolve out of that we are going to be stuck with various means for killing others in both small or large numbers.
Oh and as far as I am aware the bren has always been considered a light machine gun, which is, in it's current incarnation the designation. at about thirty pounds much too heavy to classify as an assault rifle. It has a heavier barrel to sustain higher rates of fire than an assault rifle.
