a Chinese private security group, supplementing their QBZ-95s. QBZ-97A (5.56 mm assault rifle) This variant is a QBZ-97 with the addition of a three-round burst mode and a bolt hold-open device; it also differs from the QBZ-95 and the QBZ-97 by the shape of its grip, now missing the "front grip" part in front of the trigger guard. QBZ-97B (5.56 mm carbine) This is the carbine version of the QBZ-97. The official distributor of the QBZ-97B assault carbine on the international market, Jianshe Industries (Group) Corporation, advertises and sells it under the denomination "5.56mm short automatic rifle Type NQZ03B (97)". QJB-97 LSW (5.56 mm light support weapon) The light support weapon model of the QBZ-97 is chambered for 5.56×45mm NATO ammunition instead of the original Chinese 5.8 mm cartridge. QBZ-95-1 (rifle) The new QBZ-95-1, also called the QBZ-95 "Gai" ("改"; literally: 'modified'), addresses several reliability and ease-of-use issues, and has improved ergonomics. The QBZ-95 variant titled "1" fires the heavier 5.8×42mm DBP10 round, and has a heavier, longer barrel and a redesigned muzzle brake to use it. The "1" variant has an altered butt stock, trigger guard, and a repositioned thumb fire selector switch above the pistol grip. The carrying handle has retained the Chinese quick release mount rail. In addition, bullet casings eject to the front (1 o'clock position from the barrel) of the weapon, allowing left-handed firing. Also, there is a bolt release button located behind the magazine latch. It was observed undergoing testing and evaluation in early 2010. It was later introduced into service, replacing the original QBZ-95 assault rifle. The original QBZ-95 rifles are being handed down to second line and reserve troops, while front line troops receive the QBZ-95-1. The QBZ-95-1 is scheduled to be replaced in the near future by a new assault rifle known as the "QBZ-191". QBZ-95B-1 (carbine) Improved version of the QBZ-95B with barrel and ergonomic enhancements of the QBZ-95-1 in the carbine platform. QJB-95-1 light support weapon (LSW) An improved version of the QJB-95 LSW with the ergonomic enhancements of the QBZ-95-1 in a squad machine gun platform. Civilian variants Two sporterized, semi-automatic-only rifles based upon the QBZ-97A assault rifle and the QBZ-97B assault carbine have been developed for the civilian market, the Type 97 rifle and the Type 97A carbine. They are chambered for the .223 Remington and 5.56mm cartridge and are fed by STANAG magazines. Type 97A carbines
