Problem Solved! Bought a G&P M4A1

Just watch for motor height with the adjustment sometimes getting loose and rotating out (locktite the motor adjustment screw, set the motor height and it'll be fine) and gears.

Might as well just take it apart and put the gears where they belong (in the garbage) then put some gears in there that don't suck (ie. any gearset other than OEM G&P).
