I just recently got one, and oh boy let me tell you, this is one impressive system. First we gotta start by saying that this gas system can be taken out and put into any version two body. So if you don't like the polymer then there's your new route to take. But if you like the polymer then you can't chose any better gun to buy it with. This is some sturdy stuff. As for the performance of the gun, I think its awesome to say the least. It has range equal to that of an AEG, if not then it will shoot farther. Easily put I love this weapon. It does have its problems thought, not like they are super bad though. Since this gun doesn't have the same style or even recoil system as the KWA does, the vibration from the recoil will eventually loosen some and you will need to tighten them. Other than that there really isn't much I've had to deal with personally. Otherwise you obviously need to oil the moving parts just like a gas pistol. The only disadvantage to this gun over the KWA counterparts is that it uses a closed bolt system, meaning you have to pull the charging handle back each time you load a new mag, whereas with the KWA you have an open bolt system where you can slap the bolt catch to reload the next round. Overall this is a great buy and if you are looking to see what a GBBR is all about this is a great way to do it.
