"So let me start buy saying I didn't buy it from evike but I want to leave a review just in case someone is looking into this AEG. It is the best felt m4 for the money. It feels almost real with the metal hand guard. It doesn't feel cheap. I would say it feels as sturdy as a much much more expensive gun. With that being said it's not without its faults. The fake ambi controls are kinda cheesy but not a big deal. And I would recommend replacing the bucking. In cold weather it had some stringing issues and would double feed from time to time on full auto. A maple leaf 70° bucking took care of that. Now it shoots straight and long. Hopup works well and makes it easy to get that distance. Know for the magazines most "magpul" style mags don't fit or feed. Stick with standard NATO style and they work great. From what I've heard its lipo ready but I have not tried it past some test shots at my local shop. If you are just starting out or looking for a back up you cant go wrong for $200.

"Got the gun and I have to say the battery it comes with slows the gun down but I went ahead and got it wired to deans and am currently running an 11.1 lipo in it and it is hitting around 20 rps with a beautiful trigger response I am even considering a new motor to bump up performance. Very pleased. Also I don't understand why this gun gets such a bad rap I mean the ambi really isn't a problem for me I think it looks better than a standard m4 anyway
