Umarex H&K MP7 A1 AEG SMG

Umarex H&K MP7 A1 AEG SMG Gen.2 used, upgraded with a PERUN AB++ MOSFET and some replacement parts Bullgear CNC VFC MP7 Tappet Plate & Sector Chip/FPS Softair MP7 Air Nozzle. It was serviced about 2 years ago by Kingdom of Airsoft and has been used twice since that and I am sad to see it go. The RIF fires and was chronod just today at an fps for 221-225 on 0.32s (0.72-0.75J) although it does appear to chop some BBs every now and then although that is the only problem and if fixed then it would be as good as new. £325 collected or £335 posted
