"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.

"I have to say, I love this gun...

I got this monster about 7-8 months ago and I'll say I'm impressed.

-Metal body and gear box (not hand guard, grip, or stock)
-sturdy overall, stock wobble was fixed with a screw driver and a little electrical tape around the buffer tube
-awesome precision; little spread, especially compared to JG and CYMA builds
-Bolt catch: makes hop up adjustment so easy
-stock, period; it makes the gun -=feel=- heavy but the battery compartment and cheek riser are pretty handy
-the RIS is nice, has the option to have long rails, short rails, or no rails

although I love (_3) this gun, there are some cons (and this isn't necessarily a pro or con but the gearbox has king arms branded into it...)

-stock came off, but only needed to be screwed back in by removing the buffer tube cap
-chamber was a pretty tight fit for the stock high cap, although this is not the same for after market mags (with my experience)
-piston broke after 12000 rounds, tooth broke off and I guess disintegrated
-after some time the trigger response was off/delayed

That's what I can think of for now, hope my review was helpful. Most of the cons listed are fixable, you don't really have to hesitate on buying it.

(P.S: your gonna need some finger muscles to put the battery in)

"Hello airsoft community. I have written a review on this gun before, but that was when it was brand new out of the box. Here's an update to my opinion on this m4:


*90% metal; the rest is very durable polymer
*Has a functioning bolt-catch system, which must be used to access the hop-up.
*Super-realistic feel and look
*Descent fps of around 390
*Has a comfortable range and a nice spread---
^accuracy note^ - It isn't straight-line one-hole-on-the-target accurate, but shoots
well enough to get around a half-meter spread at 200ft.

*Has a very comfortable, ergonomic hand grip
*The stock is adjustable, rather comfy, has an adjustable cheek rest (which is removable), and also features a compartment for batteries (that you could also use for anything you want, like cigarettes if you smoke or something) The stock also has a rail on the side for whatever it may be that you'd like to put there.
*Includes removable flip-up sights (front is not removable)
*Features a customizable rail system that allows you to take off certain rails and put them somewhere else.
*The selector switch is easy to move (a con if you want something a little more tough to feel sturdy).
*It has licensed trademarks on it, making it look even more "official" and threatening. (On the 'threatening' note, don't brandish this thing in public.)
*The magazine is extremely sturdy and holds a fair amount of bbs (about 350 rounds), while looking really cool.
*Flash guard is removable (It's a 14mm negative thread. For those of you who don't know, it means "righty-loosey, lefty-tighty"). *REMOVE AT YOUR OWN DISCRETION*
*Eligible for discounts (I got mine for $220 instead of $260).
*It has a shorter barrel, making it more compatible for CQB.
*This is the sickest-looking gun I own.

Now for the bad stuff...


*Doesn't some with a battery (requires a 9.6v small type, butterfly type. The correct recommended battery is in the description).
*The battery compartment is the most difficult thing on this gun - you gotta have some wicked finger- muscle to get it off, and put it on.
*The magazine misfeeds sometimes, but it won't strip your gears if you're using the appropriate bbs. However, your gears WILL strip if you dry-fire it excessively. That's a no-brainer for all AEG's.
*The magazine also has an annoyingly tight fit in the chamber. You kinda have to have a little muscle to switch mags.
*If you don't like a heavy gun, then that will be a con for you.
*The stock fell off after some time, but that was just a loose screw. To fix it, I took the stock off by pulling the lever DOWN ALL THE WAY instead of up, and I just pulled it right off, leaving a pole for a stock. After that, I took a standard screw-driver, and screwed in that loose screw, put the stock on, and it was good to go. And if you want, you can take the rubber butt-pad off to get to a screw that holds in the strap-hook.

Over all, this is a pretty decent gun. I would cry if anything happened to it, just as I said in my previous review. The only bad thing is that the compartment is hard to handle and the mag has a tight fit in the chamber. But those are just little things that can easily be adapted to. It's worth the money I spent. Highly recommended.
