Golgy, a Sunday Gamer, reviews the Specna Arms SA-J01 EDGE AEG, that is part of the AK airsoft replicas from Specna Arms. This is mainly made of steel with other metal areas made of a Zinc and aluminum alloy with a special coating used for their finishing. This is powered by the ORION V3 Gearbox and also comes with the standard "Enter and Convert" quick spring change feature.
