I had a red dot on an AR with the same setup - I never really noticed the front sight and I'd tend to think that it would be a non-issue.If I want to add an LVPO to a flat-top AR with an A2 front sight, do I need a riser or will the front sight "disappear?"
If a riser is advisable, how tall does it need to be?

If you're going to mount an LPVO on an AR, you're going to want a mount that brings it up off of the flat top a bit anyway.
I have two ARs with LPVOs on them, and the one with the taller scope mount is actually better because it falls in the line of sight much easier when the rifle is on the shoulder. I have this mount (yes, I realize it's super cheap and not something I should bet my life on, but it works well enough for now) and it's almost the perfect height, even though it seems a bit tall to look at it.
