CA Question
 

Now , I am planning to buy a CA M16A2 Shorty , now, what is the First thing that I have to upgrade in the gearbox?

I know about CA lemons and I don't want to take chances of getting REAL PROBLEMS , so , I'm waiting on answers, Thanks :D

Use it until it breaks.

First thing to upgrade is motor, and then gears, spring, and spring guide respectively. CA motors suck, atleast get a G&P m120 or even a systema turbo depending on your budget. i wont recommend a torque motor because it would mean getting a new gearbox shell and bushings. I then recommend gear set all the way from the Guarder range to Prometheus range (gear choice is EXTREMELY important), this also depends on your budget. I recommend a PDI 150% and lastly, a Guarder spring guide. If you want some extra accuracy, get a TBB, preferably Madbull because i think it would fit best in a CA. so, to sum it up:


G&P m120 - Systema Turbo (no torques)
Guarder - Prometheus gears (preferrably non hellicals)
PDI 150% spring
Guarder spring guide
Madbull 6.03 TBB
Piston & air compressing unit, Bushings, shell, tappet plate..etc - ALL STOCK



Hope this helps
