"Well let me say first off that the rifle works well and the range is excellent. The exterior is polymer but it is so sturdy that breaking it would be very diffucult. The only issue I have with this "futuristic m4" is that it can't hold any high cap mags. I have tested all kinds of m4 high cap mags, but it seems that they will not clip in and a mid cap or lower is required.

.Very sleek
.compatible with many m4 mags
.Efficent fps

.No high cap compatability
.iron sights block view of target

I would consider getting a cheap $10 red dot for this gun, and get the $5 m4 mags that are on here.

"This is a very well made rifle, it has internal metal parts, and a strong plastic exterior.

-4 rails on top, bottom, left, and right
-Good fire rate
-detachable Iron sight
-comfortable grip
-easy eject mag
-easy battery placement
-adjustable stock

-Bad iron sights
-Mag wind is hard to turn
-m4 mags that I have tested do not fit the gun

Overall the gun is worth the money, I chose the white version so I am not sure what the grey one looks like in real life. However, the performance is definitely up to par. I would suggest to get some other gear to fix the cons.

"It handles good, quieter than all my m4. Has a nice look, my tracer unit works nicely with it, wish it came with a battery and another mag but that's fine I have those. The only thing I absolutely HATE about it is the fact that the safety is more square and not rounded because I cut my thumb on the thing, and its just a tad shorter than I would like. On my m4 I can go between everything easy. With this one I have to actually move my hand for it, its not bad I can touch it but it would be more convenient if it was rounded and 1/6 of an inch longer. Other than that this thing fires fast with my 9.6 battery and .2s! Its quiet, looks cool(got trooper white) and others I know are going to be buying one. Oh I almost forgot I wish the part that slides for the battery had a screw to hold it in place because it can slide off completely
