AR18 derivative bolts and AR15 bolts

[kal]

The question is, can rifles that use 7 lug bolts like the AR18, L85, SU16, AUG, tavor, etc, use an AR15 bolt?

If not, what are the major contributing factors that prevent ar15 bolts from being used in other systems that use 7 lug bolts? Length of the lugs, cam pin hole distance from bolt face, thickness of bolt shaft, etc ,etc?

I would say all the ones you just mentioned.
Just because the number of lugs is the same does not mean any of the other dimensions are compatible.

Same style of Johnson type bolt, but completely different execution of each system.
