Umarex Airsoft MP5 AEG unboxing, repair, upgrade and review

Another Airsoft AEG Rifle that arrived in bits and left monster. This is an old Umarex MP5 that had seen better days and needed some love and attention. It arrived in many pieces and require a rebuild on the gearbox and barrel to get it work again. With some specifically choosen upgrade parts it has been given back the performance that it deserves.
