Product Information:
If you are looking for a great M4 I highly recommend this gun. In my mind it is nearly perfect right out of the box. The internals are all top notch, the only thing that anyone may want to upgrade is the inner barrel, but, honestly, the improvement would be marginal. This last weekend I put 3 consecutive rounds fired on semi into the back of my friend's hand at a range of ~120ft (paced out after). ROF is great even with a 9.6V NiMH (20 rps), LiPOs will only take it up from there (21-22 rps). Muzzle energy on mine is VERY consistent 1.59J (I only use 0.25's, ~ 414fps w/ 0.20's). After a 100 round series the STD was _ +-0.01J (~2 fps).

The externals are rock solid, no wobble at all in nearly all of the components (selector switch only exception, probably just mine). You can pick it up by the barrel (not recommended but it happens) and not have to worry at all about damaging the gun. Happen to bash it into a tree? Not to worry, the worst that will happen is that you hurt the tree. The crane stock is solid, and access to the battery is quick and easy. Far better then the one on my VFC 416.

Battery space is limited, use Intellect or Tenergy NiMH, or L-Shaped lipos.

The weight and balance of the gun make it an excellent shooting platform, provided you aren't 12. The only thing that will limit your accuracy out to 150-200ft is your own ability.

My only, very minor complaints, are that the replica bolt looks and feels a bit cheap, the bolt catch is non-functional, and the fire selector switch is a little loose. Also, in the unlikely event that you need to get into the gear box quickly be warned that the 2GX gear box is complicated to work on.

If you take care of this gun by regularly performing standard maintenance I have no doubt that this will last you for years to come. Why waste your money on a gun that will eventually break and require hundreds of dollars of upgrades to match what this gun is stock?

Note: The best mid-caps to use are S. Arms 160rd magazines, as it is a little finicky. If you have problems with these, or most other mags, try filing down the ridge on the back of the mag-well slightly. Be sure to remove the mag-well from the rest of the gun, or you will end up jamming the gun with metal shavings. Not the gun's fault I was stupid.

Pros:
Inside and out nearly every component is rock solid (selector switch only exception)
Muzzle velocity varies by +-2 fps
ROF, 20rps w/ 9.6V
Crane stock
Precise and accurate
KWA customer service (If you find a design flaw, tell them! They have and will redesign the gun to fix it. Who else does that?)

Cons:
ALL MINOR:
Finicky with mags (easy fix)
Pistol grip could be a bit wide, I find it very comfortable though
Upper receiver is impossible to remove if the piston is ever stuck compressed, until you get at the anti-reversal by removing the grip and motor and pulling it with pliers
No functional bolt catch
Bolt looks and feels cheap
Limited battery space
Selector switch a little loose
Burns through midcaps on full auto
