New MP5 AEG released by G&G. The EGM A4 Blowback is made up mainly of plastic with an 8mm oilless gearbox bearing. This comes with a 40-round magazine so you might have to look around for higher capacity magazines. This has a 2500rpm high-torqye long axis motor and fires at 90/100ms at .2.
The latest release from G&G Armament. The TGM A4 RTB series are MP5 AEGs with some innovation on their own. The power supply is a battery set that is already integrated within the Handguard itself, no need to buy another battery for this. I cannot say if I can welcome this development as this product locks you in to buy the battery-handguard from G&G and you cannot use third party batteries.
