Description
The SHS M140 AEG Upgrade Spring (TH1016) is a replacement mainspring for airsoft AEG gearboxes, part of the SHS internal parts range. It suits players and technicians rebuilding or upgrading a gearbox who want to swap the spring rather than replace the whole assembly.
As an internal part, the spring locates on the gearbox spring guide and drives the piston through each cycle. Fitting one is workshop work: the gearbox has to be opened, the old spring lifted off the guide and the replacement seated correctly before the shell is closed. With the gearbox apart, it is worth inspecting the guide and piston at the same time.
The spring carries the SHS model reference M140 and the part code TH1016, so it can be matched against an existing build or reordered by code.
