Do any of these changes to scopes fix the issue of armor clipping into the sights, or is that simply an armor issue?

We are investigating this. It is sadly an armor issue. When we go into ADS, our armor clips in due to animation, because we're not bringing the weapon to our eyes. We're looking into that, and we're planning on releasing a temporary fix for this for 3.23. It's not final yet. We're looking into other options to make it a permanent good solution, because the current solution has a few not-so-pretty things about it, a few issues. In the future there will be the perfect no-clipping, hopefully. We'll look into that later on.
