Any opinions on this rear sight?
I bought it & am awaiting delivery but have zero experience with it!
I have two KAC USMC USGI sights & love them but thought I’d try this one on an impulse.
How accurate are the elevation presets especially when when used with a 16” barrel with a fixed front sight?

I’ve used the GGG mad rear buis with adjustable aperture for quite awhile and have them on all my AR’s. I like them better than any other rear buis. They are accurate enough for me but I don’t use them on any barrels longer than 12.5”.

That mirrors my experience as well.
I have one on a 16" 9mm Carbine with fixed carbine front sight and one on a 9mm pistol with a YHM flip up front sight.
I like the option of having everything from essentially a ghost-ring system to a narrow aperture peep with just the turn of a dial.
Try one. I think you'll like it.
