Magpul Masada PTS gearbox upgrade?

[Michau]

Hi,

I currently own a Magpul Masada PTS and was thinking about replacing the gears inside the gearbox. What would be a compatible gear set for it as it is a modified gearbox? Planning to put in a high torque gearset, and possibly replacing the motor with a high torque motor as well and maybe a m100-m120 spring (nothing overly heavy).

I understand some parts of the gun uses proprietary parts and was also wondering as to which parts these pertain to and has Magpul begun releasing these as spares yet as the gun came out quite some time ago now.

Thanks,
Michau
