For over a decade, the M4A1 has been the de facto rifle for many factions of the United States Special Forces. An updated version of the venerable M16 service rifles, the M4 is based off it's predecessor's proven design. The M4A1 is employed by several U.S. military units, including the U.S. Delta Force, U.S. Navy SEALs, and the U.S. Marine Corps. The M4A1 Carbine is especially favored by Counter-Terrorist and Special Forces units for close quarter battles because of the carbine's retractable butt stock that has intermediate stops allowing versatility without compromising shooting capabilities.

The light weight Echo1 M4A1 is designed for fast action. It's sighting system also features dual apertures. These unique characteristics make it a very versatile weapon and very useful in urban warfare situations.

Thanks to it's popularity, the range of options available for the M4 series airsoft guns are endless. This robust rifle can fulfill nearly every tactical role from close quarters battles to long range combat.
