You need a LOT more than gears to get an M150 to run. I'm going to assume you have a version 2 gearbox. If you just want the velocity of the M150, your money is far better spent on accuracy and rate of fire upgrades than on more muzzle velocity (FPS.) However, let's assume that you are building a DMR of sorts. You will need:
* indicates it is a necessity.
Prommy triple torque gearset*
At least two sets of shims (you need PERFECT shimming)*
Systema metal bushings*
Systema Magnum Motor*
Prometheus Hopup chamber
Prommy hard hop up bucking*
Deep Fire titanium piston (the only non full metal piston I'd trust at that velocity)*
Systema mechbox shell*
There are quite a few other things that would need to be upgraded-to name the least, rewiring, a new cylinder, new trigger assembly, a mosfet with active braking, a new air nozzle, reinforced tappet plate, a low resistance selector plate, a new cutoff lever, a new anti-reversal latch, a solid metal spring guide (no bearings!) a new pistonhead (preferably a Prometheus aluminum) a new battery, at least a 10.8 v battery, an Ajax STS (shock transfer system) and preferably a tightbore barrel. That is to run 500fps with guaranteed reliability. There are cheaper options, but I can't guarantee their success. Remember, once you have enough muzzle velocity to reach your target, FPS means NOTHING.
I'm sorry if you feel patronized-I don't know what level of skill you are.
