"I got mine yesterday and i was very exited to test it out but when i was about to shoot, it didn't worked. it was something wrong whit the hop-up and more. Im sending it back and have to wait 2 weeks more to get it back again ;( I hope it works then.

"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

"BUYER BEWARE: My friend and I both bought this exact same gun, and both had problems with our pistons being stripped. Mine will shoot one BB for each five pulls of the trigger. Currently sending it back, and will give an update as to how it turned out. As for my friend's gun, it shoots beautifully (after being sent in for repairs twice). It looks great, feels great, and performs better than many "name-brand" AEGs that I've shot. Here's a quick list of pros and cons of this gun:

Mostly metal- the parts that HAVE to be metal are.
Adjustable cheek rest and six-position adjustable stock.
Pretty good rate of fire and is accurate at about 120 feet.
Very solid gun as of yet (I abuse my guns pretty badly during games).
Flip-up iron sight. NOTE: The part you aim through can be spun around. DO IT.
Nice weight, not too heavy, but not in the least bit light.
Dust cover will stay closed on this AEG. Many fling open, this does not.
Auto-winding mags fit in this gun.
Side and top rails!!!

Huge orange flash hider on the gun that doesn't want to come off. Reverse-thread.
The battery is put inside of the front hand guard and is a very tight fit.
Only the $30 Matrix battery for hand guards will fit. Nothing else will fit.
You have to unscrew the bottom rail to remove the battery (don't put it on).
Sensitive selector switch- will move ever so slightly when running.
Storage compartment in stock is very difficult to open. Breaking it in takes forever.
My stock fell off after about a week. Easy fix for anyone who knows airsoft guns well.
Had to send my gun in twice in order for it to be as awesome as it is.
The mag that comes with the gun broke on both my friend's and my gun. Oh well.
I don't like the one-point sling, I need both.
Tight fit for the magazines- recommend the G&P High RPS 130rd Mid-Cap Mags.
The handle on the box is very weak- mine broke off (not with my gun in it though).
The battery is exposed to the elements, small openings on the rail it's in.
Hand grip finger slots don't really line up with my fingers at all.
Very sensitive hop-up. Spend a long time getting it in the right position.
Not enough pros.


Pro tip: Shave off the front of the bottom rail where it hooks to the gun- you can use it then. Not recommended unless you plan on keeping the gun. Have someone who knows how to use a saw to cut it off, and a carpenter's knife to smooth off the edges.
