The Marui G36 Shorty, more popularly known as the MC-51, was developed in England based on the G3 series Assault rifle. The MC-51 sub-machine gun is a unique rifle; it has a compact size of slightly over 600 mm in overall length, yet uses the full-power 7.62 x 51 mm rifle bullets. Tokyo Marui has reproduced the unique style of the rifle by developing a new internal mechanism and the adoption of the powerful EG700 high torque motor, making the MC51 Model gun the most powerful sub-machine gun in game shooting. The MC-51 can also accommodate a large capacity magazine (500 BBs). Metal parts include barrel/muzzle, magazine, bolt, trigger, firing selector, retractable stock, front and rear adjustable sights. An excellent all-round weapon! Functioning all metal charging handle.
