"Wow, this is an amazing gun. I have owned mine for some time now and have had no issues with it. It is powerful, accurate, cool as all heck, and overall is beast. The only problem with it is the forward assist, bolt release, mag release, etc. are all plastic. That makes sense though, because the gun is NOT a full metal blow back. It comes with a 1500 9.6 volt stock battery. I have mine chronographed, and it shot 400 fps and 14 rounds a second. The upper, and lower receivers are polymer, but don't freak out, it is good polymer. Besides, you have to pay an extra $100-$250 for full metal blow back. The stock stinks, it is just a basic crane stock with battery storage, and it isn't all that nice. I would replace it. Overall, for a high quality but low budget ready-to-go-out-of-the-box kind of gun i would give this four out of five stars. This is an excellent buy!"
