Good spring. Works well
Ordered whole gearbox for my AEG.
After some time received originally packed
Gb.V9
Got plenty of tries of fixing old one, however there weren’t recently any nozzle that fit original HU chamber on entire internet.
Order from SIXXmm solved everything.
Gearbox and wiring is plug and play.
Just unscrew old one fit new, and you re ready to go.
So if you have problems with piston tooths.
Shimming , or simply want have spare one to rely 100% on your gun especially at big events or long trips.
Don’t wast your time , pick SIXXnm as your airsoft mate.
