I'm planing on upgrading to a marksman rifle
 

I've decuded that I want a marksmen rifle. I plan on using the new CA36 as my base, and then upgrade it to make it more precise.

Here's my planed upgrade list based on the input guys from a diferent forum have submited, I'm just looking for a second opinion on it:

Systema helical Enfini torque up gearset-piston included(over-kill but what the hey)
Systema M130 spring
Systema V3 spring guide w/ bearing
Systema V3 silent head set
new Hop-up buking
KM TN barrel
Maybe a Systema super torque-up motor (If I ever find out the shaft length of the CA36!)

Is there anything you guys think I left out? And I hear that CA gun are not good for precision shooting. Why is CA not good for this? I know their hop-up isn't the best but I'll be replacing that and a lot of other things.

Maybe a 9.6V or higher battery to reduce the time between the trigger pull and the piston release, and definitely as high a mAh battery as you can find since your are putting in a reasonably heafty spring.

I wouldn't use an m130, thats for sure.... go with a PDI 170, or a TOP 190. Better springs, easier to compress, easier on batteries and mechboxes.
