Room for improvement April 24, 2012
Reviewer: Jesse MacDonald from ME, United States  
Let me start off by saying, this is my first AEG. I really like it, it feels great and shoots pretty well right out of the box. It is very nice for CQB but not so hot for engagements at longer ranges but that's to be expected from an M4. Either way, it is a nice gun but I'm already planning to put a fair amount of money into upgrades to make this gun more consistent i.e. Tight bore barrel, RIS, PEQ Box and a couple other cosmetic features.

Pros:
Great beginner gun or intermediate
Comfortable to hold
Full Metal construction
Nice kick
Good FPS

Cons:
Battery is a pain to get in and out
Inconsistent accuracy (Big barrel)
Mag is a bit wobbly

Other than those, nothing really.


Just a few more things, the hop up is easy to access which is a plus and easy to adjust. And as usual.. Don't use the BBs in the box with the gun, they are low quality and can jam and even damage your gun.

Rating: 7/10   Certainly a good buy, I don't regret it!

Best gun February 14, 2012
Reviewer: Daniel Medeiros from myrlte beach, SC United States  
This gun is absolutly amazing!!! i've been using it for over a year now, have put over 75,000 rnds through it and it still works beautifully!!! I even use a 11.4 lipo battery with the stock internals, and there is no wear yet. Simply amazing....I would buy this gun a hundred times more if i could...best gun on the market

wrong December 22, 2010
Reviewer: santa from mexico  
the guy in the video has a different gun. if u look at the part 1 it is plastic and comes with alot of attachments and is 260 to 280fps. i have this and mine is shooting around 390 to 415fps with a .20 gram bb and 900 to 950rpm because i bought a 9.6v battery.


if you want to upgrade the fps on an electric airsoft gun you get a bigger spring or get a higher voltage battry.  maH on a battry doesnt increase fps it increases battry life which is good to.

overall this gun is a monster with a 9.6v battry
