After opening up the mechbox on my ECHO-1 G36c (and twitching at the sight of how they over-lubed it) I decided to test the shimming and upgrade the mechbox with a new spring. This was before I read skruface's stickied guide on upgrading.
After some failed attempts at installing my GUARDER SP120, I ended up with a broken spring guide (only the side wings). I reinstalled my mechbox with the normal spring, and it works like a charm. However, now I plan to buy a new spring guide and bushings to complement my spring upgrade for more durability. Thus leading to my next three questions:
1. Does anyone know how compatible these parts are with ECHO-1's products?:

http://www.wargameclub.com/pcart/sho...05_cat_Guarder Guarder Spring Guide for Gearbox Ver 3
2. If not, what do you/your people suggest?
3. Does anyone have or does anyone know anyone that're selling these parts locally? I find WCG's shipping rates a real ripoff from what I'm used to seeing.
Just as a side note, now I learned how much more convenient it is to have an actual TM product instead of a replica.
Externally it looks the same, but internally it's a different world.
