Things I liked: It is a well built mag with a little tighter fit than the Hi cap mag that comes with the KWA M4A1. Better than the high cap mag because there is less wobble and no bbs ratteling around making noise.
Things I would have changed: NOTHING...
What others should know: Buy lots of BB's!!!
Things I liked: If you are wondering the best lipo is ta firefox 11.1 V 15C 1600 mah. No bigger than a 15 cell because there are grooves in the hand guard and the bottom of the barrel is flattened to accomidate this battery.
Things I would have changed: An operational bolt catch would have been nice...But that's just nit picking because this is by far the best aeg on the market!!!
What others should know: Mine came with an M150 spring shooting 490 fps...a little strong for most but an easy fix.
Things I liked: Nice fit but after a few times using it I found bbs started double stacking.
