The Field Package adds a 9.6V butterfly battery, wall charger, and extra 300 round high capacity magazine (for a total of 2).
The King Arms Nylon M4 CQB/R adds compactness to the versatility of the M4 RIS, making this the ideal gun for Close Quarters Battle or similar tight situations. The addition of the Crane stock enhances the compactness of the gun, giving the user greater mobility. King Arms utilizes nylon fiber for its plastic components, which is far stronger and more durable than those airsoft guns that use ABS plastic. The King Arms RIS is also an ideal gun for smaller or younger players.
