SMG stands for submachine gun and the name describes the weapon perfectly. SMGs are automatic weapons but not the full size, weight, and caliber of a rifle. They are lightweight and shorter in length than a full sized machine gun. They use pistol ammunition which is why they have also been referred to as machine pistols. Because of their maneuverability they are an excellent choice for close quarters combat. Common submachine guns include the MP5, UMP, Thompson, UZI, and P90. For CQB skirmishes an SMG style airsoft rifle will suit your needs perfectly. Our auto electric guns are fully automatic and feature a high rate of fire for maximum effectiveness. Also included are machine pistols, which are stockless or ultra-compact rifles that typically use rifle-style magazines such as the M4 mag.
