4 of 5 Good Buy September 10, 2013
Reviewer: Luis Fernandez from Beloit, WI United States  
The gun is great for its price. I love the weight and feel. It feels like a real gun other than the polymer lower receiver which is plastic on lots of real guns anyways. The slide sounds great and looks great when shooting. It slides smooth and fast. It has adjustable sights and hop up for maintaining good accuracy. I recommend adjusting them when you get it as they can be slightly off when you get it which is no big deal. Its ok on gas, gets about 5 to 6 clips on one thing of co2 which is about 80 to 96 shots. Im not a big fan of the trigger, it feels good but the pull feels weird to me. Its not a big issue just gotta get used to it. I also noticed that the slide lock will lock back when the gun is a little low on co2 bout the 4th or 5th magazine through. All you gotta do is hold the slide lock down, its not hard. Other than that this is an amazing gun and I am so happy I bought it. Thank you AirRattle!
