Airsofticus does a review of the Specna Arms licensed Rock River Arms SA-E03 EDGE Aster (MOSFET equipped) AEG... "Here is my review of the Specna Arms SA-E03 Edge Aster. 7.4v battery vs 11.1v battery comparison, and mag compatibility with Specna Arms SA-03 (which I own- Specna arms mag, Cyma mag, and G&G mag). The Replica is full metal, with 363mm 6.03 precision barrel, reinforces Orion metal gearbox, rotation hop-up chamber, steel gears, aluminum nozzle, and integrated v2 Gate Aster MOSFET."
