I got this gun a few weeks ago and it it awesome!! Its everything it says it is and the accuracy is amazing! The accuracy is better than I've seen in most sniper air-soft rifles that i've seen and used. If i put a scope on this gun its range would increase to about 200-250 feet. I can currently his a target in the center 4 out of 5 times with the iron sights on this gun at about 150 feet. The hop-up is very easy to get to and i can change it whenever i need to. The gun also hurts like a B***H! I was in a war and i let a friend use this gun and he shot he in my left arm 3 times and i was wearing a sleeveless shirt under my tac vest and the shots drew blood on my arm an my friend was about 100 feet away. Also the gun is very convincing. I removed the orange flash hider and put a black one on and when i went to the shooting range i accidentally took my this gun instead of my real M4! Yes its that real! The weight and look are identical the plastic pieces are the same a a real M4 and everything! The only problem that went wrong was my fault. When i ordered the gun i got the wrong battery thinking the battery connecter would be inside the hand guards like most of the M4's but it was in the buffer tube and the battery i ordered didn't fit in the buffer tube so i had to get a friend to rewire the connecter to the hand guards so that i wouldn't haft tape my battery to the outside of my stock. Also in the manual that comes with the gun it shows the battery connecter inside the hand guards!(WTF?!) ya so I'm not sure what went wrong there but be warned the battery connecter is really in the buffer tube. And one more problem that I'm not sure if I'm an idiot or its a problem. Anyways the crane stock doesn't come off like other crane stocks. I though i would just lift the position shifter and slide it off but it wouldn't work so i stopped screwing with it and i need to look in the manual for how to get the dang thing off. Other than those 2 things the gun is amazing i just wish air-soft GI had it in tan, and i highly recommend this gun to anyone thats in that mid to high level of air-soft that wants a that will keep your friends on the other team looking out for you, this gun will make you a threat!
*just like real M4
*hop-up is easily accessible
*VERY GOOD range
*the sights are real
*battery connecter is in the buffer tube. NOT THE hand guards!(just make sure you get a battery that will fit in the buffer tube and you'll be fine!)
*the crane stock doesn't come off like other crane stocks, I'm still not sure what to do but im probably just doing something wrong.
