I consider the AK as the lowest end of assault rifles. They're junk! Cheaply made, ugly, and have a tendency to misfire. I guess they're only use is to third world dicks who can't afford the good stuff!
Er......I have a Romanian AK clone (stamped receiver....SAR1) that with the addition of a 50 dollar fire control group, a little sight alignment, and a $2 recoil buffer is a "tack driver" at 100 meters, and I've run 5000 rounds of everything through it, US, Russian, Chinese, Yugo surplus........ all kinds of ammo through it, and have never had a jam or misfire.......I clean it once a year whether it needs it or not, and if the SHTF, it would be the first gun that I would grab.......Total investment $297.
There is a reason that it is arguably the most successful design in combat arms in the past five decades........
ON EDIT: I also have a Bushmaster AR-15 20" A-4, and although it is a fine rifle, and a versatile system, I'd still grab the AK first
