Arma 3 RCO ARCO ERCO ACO scopes/sight

A brief video regarding choice of scope/sight to use in King of the Hill.
For most engagements you probably just want to stick with the red-dot only ACO sight (non-magnified) as the RCO scopes red-dot sight is so high up compared to the rifle barrel that your shots will always land a tad lower than you're expecting (up to approx 100m).

Landing high/low depends on many factors, like the zeroing of the sights and height over bore.
The red dot is zeroed for 200m and is mounted higher.
The scope is zeroed for 300m and is mounted lower.

Did the ERCO misalignment got fixed? I think it looks the best, but sometimes feels wierd.
Its especially visible on the Zafir.
