Not as reliable as so many have been led to believe, though I know this is not the norm either. From Iraq:
This can and has happened with almost every firearm in existence.
And we have no way of knowing the condition of the weapon or the ammunition.
Arab 7.62x39mm is notoriously unreliable and can be dangerous.
Could it be? An AK Jams And Later Explodes??
Glock makes AKs?
(ducks and runs)
Oh man, that’s looooowww.
Thats Right.
So… Do you do much business with regard to pistol shooting instruction or do folks have you figured out?
Ummm … huh? 
Of course it can, but the AK is supposed to be foolproof. 
I’m a little confused myself. Can you clarify your question?
Sounds as though he likes Glocks?
Ohhhh … sorry, wasn’t trying to slaughter any sacred cows. Just making a funny.
FWIW, if I wasn’t carrying an M&P, I’d probably go buy a Glock 19 as my “EDC.”
squib?
Check out the comments section. I think everyone with the exception of mabey two posters were absolute idiots.
And the ones wishing contractors dead should dive into a wood chipper feet first.
I would bet is is some craptacular ammo related issue. Proabally some high-grade Iraqi ammo.
You should go to the hospital.
I think your funny bone is broken.
Video sites aren’t known for being repositories of critical thinking.
Look at it this way: The people making the idiotic comments probably have uploaded video footage of themselves (or their buddies) firing bottle rockets from their anus.
I don’t really get too offended if someone like that calls me an idiot.
There may have even been a “bloomin’ onion” video or two.
And yes, losbronces, he was joking about Glocks KB. Lighten up.
The most common problem (if you can call it that) I’ve had with AK’s has been a failure in the primer to detonate. It happens to me once about every 1000 rounds.
Some less common problems are the bolt not stripping a round out of the magazine (getting hung up) and a magazine that is for whatever reason dimensionally incorrect (damaged, or just came that way from the factory).
AK’s can also suffer from the same catastrophic ammunition failures you’ll find with all firearms.
I have no doubt that American/Western ammunition is produced under better conditions than combloc stuff. You can directly act on that bolt/carrier on an AK, and that makes a world of difference.
