"First impressions, great weight and external finish like everyone else has noted. The Polymer or nylon fiber in the stock and motor grip is high quality and the stock has no wobble.

The rate of fire with a 7.4 is amazing, and sounds great too. There is no high-pitched "electronic" sound, just quick, loud pops. Something to note, is that with the 7.4 in the buffer tube, the stock doesn't retract all the way. The minimum length with the battery in is at the "3" mark.

The Sight that comes with this gun looks and feels great too, and the dial to turn on/change brightness is easy to turn unlike some others. Only thing with this sight is that highest setting is not at all that bright. It'll surely do the job, but was a little muted when I played a snow battle this past weekend.

I added UTG 3x flip-up scope magnifier to the setup and its quite beastly for outdoor games.

Also, the stubby grip is a little wobbly. This may or may not bother you, either way it's not too much to invest in another grip.

The rail handguard comes with full trademarks and looks and feels real nice.

The range /accuracy on this is okay. My cyma ak74 outranges this gun, probably to the difference in length, but even so I'm a little let down by the lack of range. Perhaps I just need to switch to .25s and turn the hop-up up a bit.

Overrall the gun looks and feels great, and the rate of fire makes it a monster. It is ideal for cqb, but can hold its own for sure in outdoor games as well, perhaps with a tweak or two. 5/5

"got it as a gift for myself. proved to be really good. now everybody's jealous because of the high quality externals. lets get to the pros and cons

-superb externals
-lots of trades (trademarks)
-very fast out of the box with an 11.1v (32 rps)
-great internals, at first

-gears stripped within the first 600 rounds
-mags are somewhat wobbly
-not all that great with accuracy

if you want a gun that'll shoot fast and look great, this is it. if not, just save your money and customize your own. overall, this is a great gun. the only really bad thing is the gears.

"Hands down best AEG I've owned to date. The externals are perfect. Performance is stunning. Running a 7.4v 1400mah lipo with no problems.
