Some tips for installation:
- If you want to install M130 spring, please remove piston head bearing. Spring wont fit. Or cut about 1cm of the spring.
- We do not recommend lipo battery 11.1V due to high currents, which can cause contact tan.
- Spring in the gearbox can be changed only before inserting into the body of weapons. After that, this is not technically possible, because the rear part of the body usually has not hole for spring remove.
- The warranty period is two years. But replacing of the spring is very easy and we can keep an eye on the customer exchange to extremely strong. It can shorten the life of the internal parts or completely damaged. For this reason, the warranty is on the product mistakes only. Not on the common wear (for example, worngears, trigger contacts the piston .. etc.)
