G&Gs Combat Machine or CM series are one of the best series of guns for beginning scrimmagers on a tight budget and technicians looking for base project guns. The base performance of these guns is at an acceptable level for competitive play and the standard design leaves their upgradability wide open. The Raider  is a great base gun for any scrimmager or airsofter looking to cut his airsmithing teeth. These guns are wired to the back and the battery is stored inside the Crane style stock. The rear placement of the battery allows G&G to include a rail system for the attachment of accessories. The body, grip, RIS, sliding stock, and the bulk of the rear sight are made from a strong and flexible nylon reinforced polymer while the rest of the gun is made of metal.
