CM031 carbine replica
CM031 is made of high quality metal and ABS. The top cover, outer barrel and sights are made of metal, while the receiver, stock, front grip, pistol grip and some internal elements are made of high quality ABS. Full metal V3 type gearbox is very durable and hard to damage, and the initial muzzle velocity of 360 – 380 fps does not put a stress on the internals.
