Restore your trigger response
Over time the stock wiring and trigger contacts inside a Version 2 gearbox carbonise and wear, adding resistance that saps performance and leaves the trigger feeling mushy. The ASG Ultimate rear-wired switch assembly is a straight replacement that brings back sharp, reliable trigger action.
Low-resistance Japanese silver wire
ASG’s Ultimate range uses high-quality silver wire produced in Japan, chosen for its low electrical resistance. Less resistance means a more efficient flow of current to the motor, translating into a stronger, more consistent response every time you pull the trigger.
Built to handle the heat
The switch components are made from heat-resistant compounds so the contacts stand up to the demands of high rate-of-fire builds and sustained skirmish use, improving long-term reliability inside the gearbox.
Rear-wired for stock-tube batteries
This is the rear-wired configuration, routing the battery lead toward the stock for crane stocks and buffer-tube battery setups on M4, M16 and other V2 platforms.
Fitting and servicing
Installation involves opening the gearbox and suits confident techs. If you would rather leave it to the experts, our Kent airsoft repair service can fit and test it for you. Find more internals in our airsoft accessories range.
