This variant is a QBZ-97 with the addition of a 3-round burst mode and a bolt hold-open device; it also differs from the QBZ-95 and the QBZ-97 for the shape of its grip, now missing the "front grip" part in front of the trigger guard. This weapon is the only QBZ-95 variant to have seen commercial success and military use outside of China; QBZ-97A rifles are in use by 911 Special Forces of Cambodia Special Operations personnel.[2][15
