This M4A1 AEG by King Arms is extremely durable and reliable. Unlike some of the other rifles in its price range that are made of plastic, the body of the King Arms M4A1 AEG is made of a durable and light-weight nylon fiber. The barrel and gearbox are full metal increasing durability and performance. This rifle comes with fully licensed Colt trademarks engraved on the receiver. The carry handle can be removed to reveal a picatinny rail for mounting optics. Comes with a 300 round high capacity magazine. The gun comes packaged in a nicely desinged box and packaged in form-fitted, high quality styrofoam. If you are looking for your first AEG and want one that will perform well but not break the bank, this is definitely a great choice. Battery and charger sold separately.
