First & foremost, hi! It's nice to find such a seemingly congenial gun forum.
This question is about the zeroing process. After combing several forums, I understood that any .223/5.56mm rifle firing a certain load (55/62gr @ ~3200 fps) could be zeroed at 25 yards in order to make the bullet cross the barrel's axis again 300 yards later.
Now, I am not so sure. I am now questioning whether this data only applies when the rifle is of a certain make, the sights are of a certain height, and the barrel at a certain angle.
Given the my sights' height above bore is taller than a standard AR-15, does this mean AR-15 sights with ranging functions will not be accurate for me? Will the 25/300 or 50/200 zero paradigms work for me?
I'd appreciate any help, because I'm very confused at this point.

Beretta ARX
0-200yd sight aperture are 3.75" above center bore (roughly)
16" 1:7 twist barrel
