with an integral quick-release mount. In 2008 a new Chinese 6-24×44 tactical scope became available for counter-terrorism and other law enforcement use. The riflings for the QBU-88 differs from the standard QBZ-95 assault rifle. While the QBZ-95 has a twist to stabilize the standard 64-grain DBP-87 ball round, the QBU-88 has a faster twist to stabilize the 70-grain Heavy Ball round and dedicated Sniper load, similar to the QJY-88 general-purpose machine gun, which has progressive rifling with a final twist rate of 206 mm. A long birdcage flash suppressor is fitted to reduce the muzzle signature. A quick-detachable bipod is clamped to the barrel when required. Variants An export version called the QBU-97A is also produced and marketed for security forces of other foreign countries. This derivative utilizes 5.56×45mm NATO ammunition although, instead of STANAG magazine, a modified version of QBU-88 magazine is used to feed the rounds – and STANAG magazines will not work unless modified. The QBU-97A has recently been sighted under the designation NQU03, though it is unknown if the two differentiate in any way aside from name.
