The weapon of popular choice for very specialized covert operations are the MP-5 series of submachine guns, specifically the SD3 silenced version. With a few functional changes, this is a very close AirSoft copy of the famous yet secretly used MP-5SD3 silenced sub gun. Slightly scaled down from the real MP-5SD3, the special forearm has an extended tube and a serrated and contoured forward grip. This replica of the MP-5sd3 is definitely very special. In terms of AirSoft, this gun is effectively quiet, as it is quality in shooting.
