We're back with airsoft's World War II specialist, Neo035, as he reviews the Ares Airsoft M3A1 Grease Gun EBB. This has been in the market for years now and we wonder if there are improvements to it. The ARES Electric Rifle M3A1 (AR-SMG4) is also known as the ARES SMG-004 M3A1 X CLASS. It features a one-piece steel body, a retractable metal stock, and an electric blowback. The rifle comes with a 65-round low-capacity metal magazine and has a safety lock and full-auto firing mode. The internal components include a metal gearbox, high-torque motor, and an adjustable hop-up with convenient access. The battery compartment is located in the magazine, and the rifle has a length of 580mm to 750mm and weighs 3010g. Please note that the battery and battery charger are not included with the rifle.
