Currently shopping MPVO's for my 18" AR and put this spreadsheet together. Figured I'd share it if it helped anyone.

Obviously interested in any comments or if any of the data seems off to you. I used AI to try and generate normalized values for the last six rows but of course the optical designs may make those values wrong. My particular goal is 18x+ top end magnification but I know that's high for most small frame AR builds.

I’ve got an NX8 2.5-20 on my 6mm arc with a 14.5” barrel. It’s one some of these guys here would call my “do all” or “truck gun”. I carry it often and like the durability of NF.

I was thinking of doing the same with an 18” I'm building right now.

Currently have a NX8 4-32 on my 18” 6ARC and love it.

Thanks guys! I'm currently strongly debating between the 4-24 and the 2.5-20. Finding both in the same place to look through has been fun. Both are in cabela's in the denver metro area, but not at the SAME cabelas lol. I don't think I would go wrong either way, but its a nice chunk of change and I want to do my due diligence.
