Elite Force AEGs are OEM by Ares, and include a quick-change spring feature, and a two-stage spring guide.
The Elite Force / Ares M4 CQB features a polycarbonate body much like the G&G Raider series, but includes a flip up rear sight and the quick change spring options.

The standard M4A1 also sports a polycarb (not ABS) body and the quick change spring option.

These would be slightly more expensive than the G&G Raider and Combat Machine series. Is the quick change spring a feature that you wold find useful? Sound off below, and let us know if there's any other features you would want to see in these AEGs.
We've updated the website with New Products as well, and we'll be adding more throughout the day.
