Things I liked: The magazine is very large and can hold quite a bit, which makes it good for long rounds. The rate of fire is pretty good. Has lots of rails to mount things on it. The stock is removable for CQC.
Things I would have changed: The sights are not entirely lined up on mine. battery is tight in there. If you drop the mag the bottom cover might fall of. Should come with a sling.
What others should know: It looks awesome if you take off the top tri-rails. If you turn the hop up all the way on, the range is increased by a ton. Everything around the battery is metal. Including the safe, the battery compartment, the shutter, and the trigger guard. Battery is hard to get in. If you tilt the wire to the bottom of the compartment it fits in easier. I got this gun while it was on sale for about 50$.
