Things I liked:I love the solid feel of this gun. It's got some weight to it. Deadly accurate just with the iron sights. Also, it has a good sound when firing. UTG sure did pay attention to detail when developing this excellent AEG rifle. Things I would have changed:I can't think of one thing... What others should know:The foregrip is a little hard getting on at first, I had to really force it to get it on the rail. I had to loosen the bolts on the tri-rail and slide it foward to get the grip on. This gun is for sure NOT a toy.
