Umarex MP7A1 AEP with NEW gearbox & chrono.

Umarex MP7A1 AEP = Well R-4 AEP with license markings.The original performance was very weak (+-180 FPS = 55 m/s on average).When using the new gearbox from JG (the same for JG/TM vz.61/Mac-10/MP7), the performance increased to +280- FPS = 85 m/s.This is already sufficient performance for AEP.Measured with Guarder high precision 0,20 g BB & 7,4 V/600 mAh LiPo battery.Distance : 4,5 m.Weight with long magazine : 1375 g.

Just ordered this JG MAC10 gearbox. I hope to get the same FPS results. I already have the precision barrel and bucking from Nine Ball.

​@@firingmarius473 have you test the effective range with the new gearbox?
I wonder if it also improved the distance.
