[From the manufacturer]
The U.S. SOCOM (=U.S. Special Operations Command) is known for demanding the highest performance from any other unit in the world. The M4A1 carbine met their demands.
The M4A1, which they use daily as their main weapon, is also available as a next-generation electric gun. By using a lot of metal materials and paying close attention to details and operability, we have recreated the fearless atmosphere of the real thing.
