Overall I really like the gun, but when it first came it would not shoot at all. But I called Airsoft GI and they said to lube it with silicone oil. I did and it works perfectly. I would recommend getting a better battery because the one that it came with went low on power after just two hours of a skirmish and left my bullets arching after only going 20 feet out of the barrel. I do recommend getting a sling for it since it can get heavy (its only around 7 pounds but it feels like a lot in a long skirmish) and a bipod because this gun is great for sniping if it has a good well charged battery in it and a good scope/sight. I also recommend getting a motorized box mag because I had to do a lot of winding in a skirmish with just a regular hi-cap that it came with.
Two free handgaurds
and more rails than what you know what to do with
The cavity in the stock, where you put the battery in, is large and the battery moves around. This makes a loud sound so if you are trying to sneak it can give you away if you move the gun around too much.
