    Hi I'm trying to trade my GBB system for an AEG gearbox. The GBB system is from a WE m416 that shoots approximately 400 fps. I also have a 6 co2 mags that accompany it and 1 propane mag. The AEG gearbox should at least 390 fps. Text me at 6614370712 for a test fire video or some pics. Thank you for looking.
