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 CM16  is a great base gun for any scrimmager or airsofter looking to cut his airsmithing teeth. These guns are wired to the front and the battery is stored under the hand guards. The body, grip, hand guards, sliding stock and the bulk of the carry handle are made from a nylon reinforced polymer while the rest of the gun is made of metal.
