Have you ever used a 5-25x56 on a 14.5" carbine? It's pants on head retarded.
It's honestly a bit much for a AR-10. The 3-18 or 4-16 class of scopes are quite nice for AR-10s. I really don't enjoy having a baseball bat on top of my rifle.
I generally don't enjoy benchrest shooting with 12-15# semi-auto rifles. The 5-25s are simply too long and heavy for semi auto rifles built for dynamic shooting.
Nothing wrong with a dot + scope that isn't a 5-25. I think a 2-10 plus dot makes a lot of sense. It doesn't make sense when the 2-10 doesn't have a useable reticle and is as long and heavy as a 3-15 or 4-16.
Of course a 2-10/12 that is unusable until 4x that is also as large and heavy as a 3-18 won't sell well. It's a design philosophy problem. It was never going to sell well. That doesn't mean a well designed scope will also sell poorly.
The old 2.5-10x42 nxs is not perfect, but it has the correct design philosophy. What are the choices in this space? A $2600 Leupold?

The market for $2600 Leupolds is quite small, that's a Leupold problem, not a MPVO problem. Mark4HD with crap reticles and questionable tracking? I could do the TMR, but at least update it a little, please include some numbers on the reticle so we don't have to count the hash marks all the time? Other than the NXS, the mark 4hd and mark 5hd there aren't many choices for reasonable size and weight MPVOs that are also usable across the entire mage range.
It should be a simple formula... Smaller and lighter than a mark 5hd 3.6-18 or atacr 4-16. Usable reticle across the entire mage range. Most MPVO offerings today do not meet this criteria, which is why they fail commercially.
There aren't many sub 24oz, sub 12" MPVOs that are also usable on 2-4x.
