Wow - let's see if I can do this easily.
1] Yes it is link wear and tear on trunnion
2] Yes - that is the cocking lever that cocks firing pin on rearward stroke of bolt, where it then locks into sear.
3] Forward one is Front cartridge stop - rear one is .308 spacer, only used for 7.62 Nato configuration
4] Yes, that keeps pressure between cartridges and they are fed and locks the belt or linked ammo into trunnion area.
5] Trigger engages the slot shown - upon pulling triger sear is lifted upwards, disengaging the firing pin from the sear, allowing it (FP) to move forward and strike primer.
6] The pin has a slot in the far left end that spreads to create tension in the holes. After doing that it will not come loose.
7] That is an inspection hole that was put in Izzy guns for checking either timing or headspacing, I'm not sure on that one. It is seldom used in the Semi Auto configurationas far as I know.
Hope this helps a little - I'm sure others will add to this as they read it.
