An email correspondent points me to the Wikipedia page of (as far as I can tell) the only Iranian-designed and manufactured assault rifle.
The rifle's name?
The Khaybar KH2002.
Yes, it is named after the Battle of Khaybar, whee Mohammed slaughtered some 10,000 Jews in 629 CE.
The Iranian military does not use the assault rifle, according to the article. Instead, they ship them to be used by - Hezbollah.
