OK so after looking through all the stickies I've decided these questions are quite specific to the gun and parts i'm looking at, so please don't flame for not searching.
I bought a used G&G M4 CQB-R and it turns out the gears and piston teeth are all stripped, so, looking at all the online options, I've come down to these two choices; please let me know your opinions.
Option 1: piece together the upgrades needed from capital airsoft because its in canada, its cheaper, and don't have to wait nearly as long for shipping. These are the parts -
Please confirm if these parts (SRC?) will be compatible with G&G M4 ver. 2 gearbox.
-SRC OEM Cylinder and Cylinder Head Set for M4/M16 Series - $6
-Element V2/V3 Piston & Piston Head Set - $14
-Element V2 Ball Bearing Spring Guide - $11
-Modify M120 Spring - $15
-SRC V2 Gearbox Spring Set - $4
TOTAL: $50
I've never heard of the "Element" or "Modify" companies, anyone have experience with them?
is there anything I should look into other than these (except metal bushings) plus I just bought a new set of gears from 007
THIS is my other option, but is it really worth the extra?

Now it also said "enlarged set" which I'm guessing means a wider cylinder/piston set? does this fit into a stock mechbox casing?
SORRY for the barrage, but I need my gun upgraded and running flawlessly for Claybank and only have so long to do it, so any all all info is greatly appreciated! THANKS!
