"brought this for my jg g3 its amazing, made my fps from 340fps to 385fps

gun shoots 360fps to 380fps just like it said it would
powerful more then i thought
gun shoots farther about 20 more feet added my range

have to use .25grams instead of .20grams for it to shoot straight
makes my gearbox louder
had difficulty installing in my v2 gearbox, had to wrestle with with it for 3 hours to get it in to place!
paint chip off when shooting it overtime!

I'm satisfy over all it did what its suppose to do, but if you buy it, i warning you, you have to have patience getting it in your gearbox!
