Hey Regisvo, you fill up the barrel of an AK-47 rifle with dirt and it's going to cause problems too. The problems that I'm talking about are barrels and receivers blowing up. That has nothing to do with an AK versus M16 thing. That has something to do with proper weapon handling and safety.
As I said, I've handled them. Nothing special... just another Chi-Com bull-pup rifle. Of course that was the QBZ-97, which is cahmbered in the 5.56x45mm and uses a different magazine well and magazines. It uses the NATO STANAG AR-15 series of magazines.
I have a little bit of background experience in this field. I'm a former Gun Smith and Firearms Dealer. I'm currently a police officer and I go to just about every single firearms event in the USA. The SHOT Show is the major event. Everyone there hawks their gear and guns. Your little rifle was there. It was not the best thing that I've seen. Infact, I seen better polished turds made in the Gun Bazaars Of Pakistan (home made guns).
Once again... another showing of the photo that everyone loves....
