|Overview||Ghost Recon 2||G.R.A.W.|
The QBU-88 rifle is a gas operated, semiautomatic rifle. It utilizes a short stroke gas piston, located above the barrel, and three-lug rotating bolt. The action is mounted in the compact steel receiver, and enclosed into a polymer bullpup-type housing. To increase accuracy, the action is mated to a 640 mm long, hammer-forged match-grade barrel. The safety switch is located at the bottom of the receiver, just behind the magazine opening. The QBU-88 rifle is equipped with open, diopter type adjustable sights, mounted on folding posts. It also has a short proprietary Chinese military rail on the receiver which can accept telescope or night sight mounts.
