    "I bought this Gun about 2 years ago, I have not have any internal problems. The only problems were really cosmetic. The Stock came off, I had to screw it in twice, There is no room what's so ever to fit a battery since it is in the Hand Guard. You Have to Buy Li-Po... Not included in the Box.

    Looks good
    FPS is balanced so you can Play Indoors and Outdoors
    It is Full Metal, At least most of the Gun
    Polymer feels great

    No Battery Room
    Stock fell off... Twice
    Gun becomes Front heavy if you use Flash Light, PEQ Box

    "I bought this gun awhile back and at first i was in love with it! I went to my first outdoor game with it and it was doing a great job great rpm great distance then after my 3rd or 4th time reloading something went terribly wrong inside every 10th bb would just fall out of my gun and the rpm went wayyyy down. so i called up evike and they told me a few things to try none of those worked. then to ruin that day on the field the screw that connects the buffer tube snapped in half and messed up most of the stuff inside the gun. when the stock hit the ground that also broke.

    super cool gun
    best for indoor use
    looks good
    a little heavy
    comes with a cool mag and a cool stock

    cheap screws something was wrong with my internals hopefully it was only my gun
    it was just kind of cheaply put together
