The QBZ-95 (Chinese: 95 pinyin: 95 Shì Zìdòng Bùqiāng; literally: "Type 95 Automatic Rifle") is a bullpup-style assault rifle manufactured by Arsenal 266, part of Norinco and Arsenal 296, under Jianshe Corp, for the People's Liberation Army, the armed forces of the People's Republic of China, People's Armed Police (para-military police), and other Chinese law enforcement agencies. This weapon uses a newly developed ammunition type of Chinese origin, the 5.8×42mm DBP87. The QBZ-95 consists of a system of firearms using a common design. This family includes a carbine variant, a standard rifle, and a light support weapon.
Variants:- QBZ-95 (Rifle)
This is the Chinese standard-issue version of the rifle, chambered for the 5.8×42mm DBP87 round.
Due to issues associated with the original design, the PLA began a program to improve the Type 95. Lead designer Duo Yingxian , now retired, stated that the project was currently in progress by some of his students. Goals for the Type 95 upgrade program include the following:
1. To improve the rifle's ergonomics and fire controls.
2. To chamber the rifle for a new type of ammunition with double the effective range.
3. To add a quick-firing, domestically-produced grenade launcher.
The upgrade program resulted in the improved QBZ-95-1 variant.
QBZ-95B (Carbine)
QBZ95B short assault rifles
This is a shorter and lighter version of the standard rifle. From pictures seen the QBZ-95B is seen issued only to naval officers, possibly due to the limited room in naval vessels that would prohibit the full length rifle being used in close quarters. Its shorter barrel prevents a grenade launcher or bayonet from being attached, and it has an AKS-74U style muzzle booster. The carbine may also be in use with special forces. The carbine lacks a forend and instead has a foregrip, with the front iron sight built into the carrying handle.
QBB-95 LSW (Light Support Weapon)
QBB95 squad machine gun
This light support weapon fulfills the role as the squad automatic weapon. It's in the same respect as the QBZ-95 Rifle with modified longer and heavier barrel, higher firing rate, heavier cartridge and is equipped with larger 75-round drum magazine
