Things I liked: i love that it has just the right amount of weight, 2 metal 470 round magazines, great fire rate, long battery life, and adjustable rear sights.
Things I would have changed: the one thing that annoys me is that the safety is really crappy. it is hard to turn it on and way too easy to turn it off. maybe i screwed it up somehow, but if i did it didn't take much to do so. DO NOT let this prevent you from getting this gun because it is just awesome.
What others should know: I am new to airsoft but even i can tell that this is a great buy!
