    "This gun is absolutely amazing. Says it shoots 40 to 50 meters on the box, I think it does more. Hard hitting, battery on mine has lasted for a week (hour a day use or so) and I could not have asked for a better primary. HIGHLY RECOMMEND"

    This is a amazing gun
    By: Jesse

    "The guns looks amazing and the rails make it possible to customize the gun a whole lot. The carrying handle/sight is removable and a great place to put a Scope. The FPS is nice and the accuracy is great. I think this is a great gun for beginners and pro players too."

    Great gun
    By: Owomba

    "This think shoots great out of the box and it feels realistic. Also it has rails and a nice crane stock all under 150. It's great to upgrade and to use as a backup just as it is."
