"Amazing gun and shoots great, I use it indoors and its great for people who deal with a lot of cheaters, it packs a pretty good punch with .20g BB's, im not sure how it performs with others. I had to adjust the hop-up a little but other than that its a laser.

"Just got this gun a few days ago and the build quality is amazing. Not super heavy but still very heavy duty. Accurracy isn't amazing out of the box, I upgraded mine with a new bucking and its much better. I played a full few games with it today - and it performed very well. It is a little loud but that can be fixed with a sorbo or better shimming. I couldn't figure out how to remove the flash hider, as there is no set screw or visible pin. Mag well is kind of picky, it won't fit gp mid caps. And the Evike BAMFs are a little small and wobble a bit. It feeds great and the full auto is pretty quick. The rear sight is kinda bad, but it works. Both the sights are removable, also there is a quick change spring system that the description does not mention. Bolt catch works great, though mine came scratched. The stock hop up nub was horrible, replaced it with a hnub. (Does not have a fuse in wiring, or mosfet) Overall a great gun for the price ($170). Would recommend to others.

"Great gun but can be better. You are paying for quality so there are small defects but nothing too major that renders the gun useless. Things like the hop up and stock gave me slight issues. The hop up isn't too good sometimes it works flawlessly other times is sucks. I`m definitely going to upgrade the whole hop up. Then the polymer stock has some wobble in it this is just a little annoying but this review is just a heads up. Like I've told my friends this gun for this price is just a base gun for you to add mods and improve it.
