PS There are Iraqis that agree with you. That is why the Ministry of Interior [police] buy Chinese AKs.
Ministry of Defense has over 1/5th [50,000+] of its force equipped with M4/M16 as of Jan 2010 with no major issues.
Except one: It is taking too long for the manufacture to deliver them. Over 100,000 have been ordered but only half delivered to date...
Thanks for the update.
