Ive read alot about how the type 89 has a "reinforced gearbox", but I cant seem to find a definitive "metal gears/bushings" statement on any review. Does anyone that has this rifle know what is and isn't metal inside the gearbox?
I want to upgrade to 400-420 fps, so I'm looking at a systema 120 spring. From what I read I'm assuming ill be okay as long as the gears and bushings are metal correct? Or are there other parts I should make sure are metal as well?
