Type 69/79 MBT discussion
Under "Variants" section, the Type 69-II's description reads:
The formal production variant introduced in 1982. This variant is fitted with a 100mm rifled gun and a primitive fire-control system. It is also fitted with a new Type 889 radio and rubber track skirt. Later variants were fitted with a storage rack on the turret to provide extra protection against HEAT projectiles as well as smoke grenade launchers
Then under "Armament" section, it says:
The Type 69-II is fitted with a Type 69-II 105mm rifled gun, with a simplified fire-control/night observation equipment.
Globalsecurity's page reads:
The Type 69 MBT was first produced with both smoothbore (Type 69-I) and rifled (Type 69-II) guns. After extensive testing, the rifled gun proved to be more accurate and had greater armor penetration characteristics. Smoothbore production was discontinued after only 150 such equipped Type 69s were built.

A second version of the Type 69, or the Type 69-II, was developed in 1983 at the No. 617 Factory. The newly improved tank included a simple fire control system, laser rangefinder, rubber shielding skirt, turret grid shield, and a hydraulic booster system for improved steering. The Type 69-II also included a double-pin rubber track plate, protection from NBC weapons, and a 100mm rifled gun capable of firing APDS and HEAT rounds.

I think the "105mm rifled gun" description under "Arament" section is prolly wrong and should be replaced with "100mm rifled gun".
