"This hop up unit is a great replacement for your stock one. very sturdy and very well build. Nub does not come in it so you must put it in your self. Other than that great fit. Clip is tricky also.

"Satisfactory hop-up unit. The bucking that comes in the package is very hard and some fitting may be required (I've had to file the wings on either side of the unit and open up the front of a few JG gearboxes to get it to interface properly), but it does what it's suppose to at a decent price.
