Here's more info on what those values do to help you make a better informed decision on how to pick the values for those:

For anyone finding this page wondering how to fix the issue, 1.02 introduced a new bool for weapons 'CanEnterIronsights'. So if you want a scope to work alongside ironsights like a PSO you will need to add that to your rifles script class to return true with that scope attached, as currently it will return false always if an optic is present.

As of latest exp patch, my custom scope on my custom rifle is excluding ironsights, despite not being in ironsightsExcludingOptics. The way it's set up, the scope is mounted above the ironsights, so that you can use irons even if it's attached, and this has worked until experimental. I'm wondering if any devs can let me know how I can get it functioning the way it was before. Thanks!

This forum is for standalone, not arma 2. As far as your issue with redux goes, did you edit the min and nominal values of the items?

Same way it works with PSO sights. You ADS into iron sights, then scroll up into scope. Here's an image to help you better understand why both options can be available since you seem to think the scope is in the way of the sights: To clarify, it seems your response is assuming I don't know what I'm doing. Trust me, I do, and the only people who will likely be able to remedy this are the devs.
