Question on strange G36C gearbox part/CA cylinder grease

I'm putting my gearbox back together for my first time and I am going to reshim/regrease everything. I have no clue what that part does/how to install it. If you guys could link me to something or explain how to install it, that would be great.


Also, will CA cylinder grease work for the piston and piston rails? (I don't have any silicone spray and I need to get my gun back together by friday)

thanks guys

Try www.mechbox.com they have some very good videos.

nvm, I got answers on another forum. I have watched those videos, but they don't show the part lol

Do you happen to know how many shims you put on TOP of the gears? (I've already shimmed the gears, I'm just not sure how many you put on top)
