KWA, you have relly done good ith AEG's! This is by far the most amazing gun I have ever owned. The full metal construction gives the gun a great feel and weight. The rait of fire with a 9.6v mini is just incredible! I have not yet tried it with a Lipo Battery, but another plus for this gun is that it's lipo-ready right out of the box! It comes with a 360 round High-capacity magazine, which is perfect for me, because like Tim, I do not really like having to constantly reload. FPS is around 385-400 with 0.25gram bbs. However the battery package is not really neccessary. Yes, it's a KWA that comes with a battery, that may immediatly jump out at you, but it's only a 8.4v battery, one that I replaced the second I got the gun. Another complaint I have is that the hop-up system is plastic. It's not that big a deal, but if you want toper performance, then I suggest getting a metal hop-up system. All in all, even with my down sides, I give this yet another astounding KWA a 5/5 rating!
