he QBU88 (also known as Type 88) 5.8mm semi-automatic rifle was introduced in the 1990s as a successor to the Type 79/85 7.62mm sniper rifle. The weapon entered PLA and law enforcement service in 1997 under the designation Type 88. Despite being known as a sniper rifle in PLA, the QBU88 is more of a military designated marksman rifle rather than a dedicated sniper rifle. The weapon was designed for aimed semi-automatic fire at ranges beyond the capabilities of standard infantry assault rifles. It is intended for rough military use, and has strong tolerance to water and dust. The rifle is also available in NATO standard-issue 5.56 X 45mm calibre version known as QBU97 (or Type 97).
The PLA began to develop the 5.8 X 42mm “heavy round” cartridge in the later 1980s for the use of 5.8mm light support weapon (squad automatic weapon) and 5.8mm sniper rifle. The cartridge is exactly same size as the standard 5.8mm cartridge, but has a longer streamlined bullet with steel core for longer range and better penetration capability. The 5.8 X 42mm “heavy round” cartridge has an effective range of 800m and can penetrate 3mm steel plate at a distance of 1,000m.
The QBU88 sniper rifle is a gas-operated, semi-automatic rifle. It uses a short stroke gas piston, located above the barrel, and three-lug rotating bolt. Action is mounted in the compact steel receiver, and enclosed into the polymer bullpup-type housing. The safety switch is located at the bottom of the receiver, just behind the magazine opening. The rifle is fitted with adjustable iron sights by default, and has a short rail, which can accept 4X magnification telescope or night vision equipment. The gun barrel is not free-floated, and is fitted with flash hider. Quick-detachable bipod is clamped to the barrel when required.
The QBU88 provides a useful supplement to the 5.8mm assault rifle and 5.8mm squad automatic weapon in battlefield. However, the rifle is not as accurate as dedicated sniper rifles serving in Western countries. User experience from the law enforcement showed that the rifle is less effective in dealing with criminals, where higher accuracy of fire is required to avoid collateral damage.
