Cheers man, it's actually getting the following upgrades as we speak, courtesy of the amazing gun-doc wKnight-
Modify Bearing Spring Guide - V3
Systema Silent Head Set V3 gearbox
Modify Air Seal Nozzle - AK47 Series

I really can't recommend this gun enough, it's only been about 2 months and it's been to hell and back with me.
