I have owned two KJW mk2's. Both of them after a while have had issues mostly with the magazines leaking, or discharging most of the gas in a few shots. They are very powerful, but inaccurate at long ranges. Without any upgrade capability, I recommend a JG bar-10.
- high fps
Very, VERY lightweight
With this gun, you pretty much have an airsoft musket.
