KH-2002

The KH2002 "Khaybar" is an Iranian designed assault rifle, derived from the DIO S 5.56 assault rifle and further developed by Iran's Defense Industries Organization (DIO). It was designed in 2001 with samples produced in 2003 with the eventual production of the KH2002 commencing in 2004. The rifle is built on what seems to be a bullpup conversion of the DIO S-5.56 assault rifle, an Iranian version of the Chinese Norinco CQ rifle, which is itself a clone of the M16-A1. It is similar in appearance to the FAMAS assault rifle.

Design
The KH2002 features a four-position fire selector lever which is situated toward the rear of the left side butt-stock behind magazine housing. The weapon is not ambidextrous.

The selector offers semi-automatic, fully automatic and three-round burst options, with the safety selection in the forward position.

The DIO promotes the KH2002 as a "low-recoil, highly accurate, lightweight" weapon, with "modular construction for easy maintenance" and a rotating bolt locking mechanism, presumably designed to facilitate ambidextrous firing, protected under a carrying handle that contains the rear sight. The carrying handle can also be used to mount optical or night sights.

The weight of the KH2002 with the long barrel and an empty 30-round magazine is given as 3.7 kg. The weapon can also be fitted with an optional bipod and a bayonet. The KH2002 appears to be made of two plastic shells, one holding the grip barrel and gas tube and the other housing the M16 type bolt and hammer.
