A review by Mister Moro covering the Maruyama Manufacturing FMG9 GBB folding gun for Hyperdouraku. He writes that the Maruyama Manufacturing's gas blowback FMG-9 is a replica of the MAGPUL transforming pistol carbine. This highly detailed model features a one-action transformation, metal outer barrel, adjustable hop-up, and detachable carrying handle. The stock is made of plastic and can be folded, while the trigger guard and grip deploy when a lever is pressed. The ejection port is on the right side of the receiver, and a Glock slide serves as the bolt. Despite its simple sights, the FMG-9 offers sufficient accuracy for airsoft games. Its compact size and unique transformation make it a fun and collectible model, especially for VIP guard battles.
