Well, it is a very sleek gun and having the 5 firing modes is great. But you gotta drill a hole through the grip so you don't have to remove the grip every time you want to change you ROF. Weird how the gun works though! When I got the gun me and my friend put my CO2 tank on and tried to shoot but all the air leaked through the barrel. So I tweaked with it and now its ok. HAVE FUN!
Overall it's a nice gun and got it a a great deal only 50 bucks off ebay.
