"This was my first AEG, and this review is based on 3 months of ownership and ~6,000 rounds of use in casual field and woodland play with a 9.6v nimh battery.

This M4 has a very nice weight which was the first thing I noticed. Definitely heavier than some of my friend's full-metal M4s, but not so heavy that it is burdensome. Due to the front wiring with mock-PEQ battery box on the rails, and the 16" outer barrel this M4 is noticeably front-heavy compared to others. Before purchasing I read several reviews that indicated little or no RIS/front-end wobble. This was not the case for mine. At least 1/4" probably closer to a 1/2" of wobble was immediately noticeable on the one I received. The cheap wobbly vertical grip included, combined with the RIS wobble was virtually unusable. I ended up ditching the vertical grip, moving the PEQ box to the right hand rail, and putting a hand guard over the top joining the top outer barrel rail to the upper receiver. This 100% eliminated all wobble and now feels incredibly sturdy, but of course it doesn't look quite right. But this was preferable to the very high amount of wobble present out of the box.

Within minutes of u-nboxing and messing around with this M4, two metal pieces of the charging handle also simply fell off. I did not drop it, I did not pull it hard, but nevertheless they simply broke off. The charging handle is still completely functional without these small pieces, but it did not make me feel great about the build quality of this M4. A piece of the PEQ box also fell off and was lost during my first woodland game with this gun. Overall I am disappointed with the quality of the externals.

However, in terms of performance I was pleasantly surprised. I have not chrono'd the gun but subjectively it easily keeps pace with $200+ M4 AEG's used by others I play with. Consistency, accuracy, and power all turned out better than expected for an M4 at this price point. I have used several brands of mid-cap and high-cap mags and all have worked and fed very well. I have no complaints about the stock, it seems sturdy and works as expected.

Overall I give this gun 4/5. It does what you need it to do, especially for a first AEG at the $150-180 price point. It keeps up in the field without any additional money being spent on it, just beware that some of the externals may suffer from being cheap, brittle, and fragile. If you are looking for a gun with no wobble out of the box, this is not it. If you are looking for a solid first full metal AEG M4 I would definitely recommend it.

"This was my first AEG over 100$. Had it for 6 months and still works like new. Deffinately worth the money. I could hit a crayola marker from 80 feet. Everything is metal and the grip,stock is abs plastic. It is as heavy as the real thing. Im still using the stock battery and its shooting 340fps with .2 bbs. Shoots about 17 bbs per second i reccomend a 9.6 2000mah large type battery for more than 20 bbs per second. Ris is very sturdy does not budge. Perfect gun for begginers or even pros. Youll love it if you get it
