Sorry Magsz, it will have a battery bag in back. All my AEGs use 1 type of battery, 9.6V 2400 mAh. I do not have to carry an M4 battery, G36C battery, MP5 battery, etc. Ergonomics over aesthetics for me. Less work when the weight is in the back instead of the front. Just think of the battery bag as a the magazine pouches they put on stocks. I plan to get a magazine pouch to see how it looks.
