So I just bought this rifle a few weeks ago and have put it through its first full day game. I am very impressed with what you get in such a small package.
First off the one I got was a lemon. The selector plate was not set properly and thus would not engage in full auto, only semi. I sent it back to Airsoft G.I. and they fixed it wonderfully (thank you!). Now that it is back I have enjoyed the crap out of it.
Diss-assembly - The videos out there say that the flash hider just screws right off without any tools at all. That is a lie. I had to get a wrench after the thing just to make it turn a little. However once you get it off the first time it is easy from then on. After the flash hider comes off the rest of the gun comes apart very quickly including the whole gear box. It is the easiest gun to take apart and put back together I have ever dealt with. This rifle is very easily customizable!
Body - The body is, as you probably know, all plastic except for the buttons. However, the rifle's internals are pretty tightly packed and the plastic material is very sturdy so the rifle is more than able to withstand typical field abuse. Other than maybe scratching the outside I do not believe the rifle would be harmed by being dropped on concrete from chest high. All three magazine release buttons work wonderfully and come in very handy. The rail space is more than enough for any attachments, however, the rifle has no iron sights. I currently am using a mock EO tech and a magpul angled forgrip on mine. I am not sure if this is due to mine having to be fixed or not but the selector switch is stiffer than any other rifle I have used.
Magazines - Here is the biggest drawback of this rifle. If you like using all hi-caps then no worries but if you like using mid or low caps well... You have some work. This rifle will accept all hi-caps but for mid or low caps you must cut a small length off of each magazine's feeding nozzle rib (not sure what or if it is named). There is a video from the Airsoft Doctor on how to do this but you can just use the hi-caps that come with the gun as a reference. Just make sure you cut off less than you think you need to otherwise the magazines will not seat in the rifle well and they WILL NOT FIRE. Aside from this, I am using king arms M4 mid-cap mags and they work great.
Internals - I have not broken down the gearbox as of yet but the internals are very well made and most all of them are metal. I have not had any trouble with the interchangeable spring and it is indeed very easy to change. I have been using the higher FPS spring for games so far. The barrel is a 6.04 mm barrel and performs great in the field. Currently I am using an 8.4v 1600MaH Intellect battery with 0.20g BBs and the rifle has just as much or more range than a friend of mine with an Echo 1 ER25 and a 9.6v 3600MaH battery with 0.20g BBs. No complaints here. The trigger is kind of an odd shape and your finger can slide off while firing if you don't have a good seat but other than that it is a smooth, easy trigger pull all the way back. The hop-up is also very easy to access and adjust.
Overall impression - the magazine issue is by far the worst problem of this rifle. Why APS didn't think of this during design I will never know. Other than that though the rifle looks great, feels great, functions great, and performs great. I look forward to seeing more of these on the field!
-Easy quick change spring
-Magazines, magazines, magazines
-Stiff selector switch
-Difficult first removal of flash hider
