I have a Kraken on my work bench right now. Man, it feels cheap but it seems to shoot decently. The poor guy who owns this says he bought it at Canadian Tire and it cost him almost $300!
I feel sorry him...The clear plastic reciever is so fragile, it's already cracked. The upper reciever doesn't stay on, it's been taped on. AK metal bodies are cheap though so that's the one benefit to going AK. The gearbox is sketch, I don't like clone gearboxes. Fit and finish is all off and there are nylon bushings. It's shooting 360 FPS.
