If you were able to save some of your Christmas money, then this item in stock at RSOV.com might just make you able to part with it. The new A&K Full Metal ZB26 Mongo's Machine AEG has a custom gearbox and motor. Made with real wood and steel throughout, its top feeding magazine has a capacity of 40 rounds and fires at 270-290fps which you might need to upgrade in case you find it underpowered. You may need more magazines to go with it since it's a low-cap but perhaps its just a typo and instead it's 400 rounds.
