||Incredible gun. It shoots 450 with.2s out of the box, which is actually way too hot for my preference. It shows that the air seal is superb, but I would have rather gotten the M100 version, unfortunately I bought it at a local retailer and this was the only one they had. The externals are great. The gun weighs about the same as the real steel (with no battery). The only bad part of the externals is the handgrip. It rotates quite a bit, and along with it the front sight. This is a problem I've heard of several other people having. Also, since the battery compartment is inside the handgrip, there isn't a huge amount of space. This also means that with the battery in, the gun should be pretty front heavy (I wouldn't know since I got mine rewired to the back, but mine is pretty back heavy. It might just be the gigantic 9.6 4200mah battery I'm using). The gun has a stock tightbore, so it's very accurate.
Matrix gearbox is incredible
Great air seal
Handguard/front sight wobble (doesn't bother me that much)
Small compartment (an intermittent problem with the M4 series
Shoots WAY too hot for me
Overall, this is a great, cheap, high end gun, but I would recommend getting the M100 version instead.
