Airsoft M4 Rifles come in a variety of styles for multiple combat modes. We have a selection of CQB (Close Quarter Battle) Airsoft M4 Guns and we also carry the full size barrel M4 Airsoft Guns for standard military simulation. All of the M4 Rifles are Auto/Semi Auto firing at a rate between 340 fps and 400 fps. These are very realistic heavy duty machines and are superior guns for any level of player. Buy your Airsoft M4 from a leader at Airsoft Gun Supply.
