This is a great hop up unit! I got it for my 7.5 Diplomat to help improve the accuracy on a gun with such a short barrel. And boy did it work! Obviously with a good hop up you also need a good bucking/nub combo, I chose to go with the modify flat hop bucking/nub combo. The accuracy is AMAZING!! Couldn't get any better. Assembly is pretty difficult and the adjustment wheel is REALLY stiff.
Single adjustment wheel
Assembly is kinda hard
Wheel adjustment is really stiff
Mine was sticky when I got it
