It was mentioned to me, by a gun doctor, that the sector gear of the gearbox doesn't matter, and that sector gears from version 2/3/6/7 etc can be used in any gearbox. I'm assuming it's the spur and bevel gear that do matter and are different based on the gearbox type. He allegedly placed a modify gear inside in place of my Guarder gear. I don't believe modify makes V7 gears.
Can anyone verify if this is true? Meaning, for example, that if I were to purchase a random V2 sector gear, it would work in a TM Version 7 M14 gearbox?
Or do I have gears mixed up and things backwards? Or is this totally wrong?
Thank you for the input
