Looking to buy a gear box for my JG g36. Right now it houses a V3. I would like to have separate outdoor (~450fps) & indoor (<350fps; current) gear boxes for when I switch from arena to field.
I am wondering what are some of the issues I should be concerned with when getting a more powerful/efficient gearbox?
1. Stay with V3?
2. Will it fit my G36? (I probably will need one from a g36)
3. Getting the same gear box & upgrading internals (spring, piston, gears etc)
4. Upgrading post-gearbox parts? (Tight bore)
5. Upgrading battery WITH gearbox?
(Stock = 8.4, can I go to 9.6?)
