"this is my first gun and I bought with low expectations and my expectations were far exceeded...I have had it for four months and it hasn't jammed once totally deserves the five stars...the mag though is not so great I would recommend getting a different magazine...but over all the gun is amazing

-High rate of fire
-looks good
-feels good in hand
-FPS is high

-Buffer tube is a little small
-Motor died on me in the middle of a game

Overall a good gun for the price. Tried to get in contact with the King Arms customer support to see if there was any kind of factory warranty, nothing yet.

"I bought this gun with pretty low expectations. Originally I was just looking for a gun to eventually gut the internals and make it into a ssg build. But after trying it out, it is actually pretty good stock. The rof is pretty good, and the trigger response is great with a 9.6v battery, and even better with an 11.1v but I wouldn’t recommend it with stock internals. The range/accuracy is meh but I usually wind up replacing the inner barrels anyways. If you are looking to get started in airsoft or just have a decent cqb gun without upgrading a ton this is a great option. I got it for 140$ on sale which they go on quite frequently.
