Shoots good out of the box but need a few upgrades to shoot awesome.
I have used this b2k3 for about six months and I love it. The stock frame is alright, but it need to be changed to get high rates of fire. The stock reg is allright, much better than the old ones, but it is still a stock reg. This gun is very light and so easy to play uptight. I love it for snapshooting. I have not had one leak or problem with the gun, but I clean it after every day of playing. The ano is kind of thin and it scratches kind of easily, especially when you dive headfirst into a bunker. It is very accurate and doesn't have much of a kick. I put a ripper frame on it, and it can outshoot my hopper if I really get on it. I haven't had a problem with chopping, though it will chop if the hopper is slow. Yeah, its not an angel, but with a new frame, it can keep up. It needs a few upgrades to make it a mean machine, but it will treat you good.
I love this gun, lightweight and it makes snapshooting a dream. It is a very good gun for the money
