Another compact AEG for Mach Sakai to go over and it is the EMG Helios Angstadt Arms SCW-9 made by S&T. Fully licensed, this AEG has most of the features that airsoft players want in an AEG these days. This has a Gen 3 Lipo ready gearbox with micro-switch trigger and quick change spring guide as well as an integrated MOSFET. It is made of aluminum alloy upper and lower receiver and free float M-LOK compatible aluminum alloy handguard.
