Strike everything but the Spring and get a TM M14 instead. TM is a good solid brand and the internals can handle a lot. I have a AUG from TM for about 8 years and besides some tuning and a spring swap to bring it to 400FPS it hasn't need any internal work. Honestly with all the parts you want to buy you might as well get a good solid brand and not have to worry about the internals so much.
A TM M14 with the $19 spring you listed comes to $454 which is $12 less then the total for just the parts you want. Look closely at what you want to buy. You are more or less dropping a TM gearbox into a CYMA and spending more money the it would cost to just buy a TM M14
As I said on your other post making a DMR takes a lot of time and money. You're better off getting a good solid brand and slowly working towards your goal instead of getting something that won't stand the test of time as well. Remember in airsoft you really do get what you pay for.
