I'm running an LPVO on my 16" 5.56 AR, and my height over bore is 2.625". I'm just curious what the average height is that you all are using.

I did a search, but didn't really find what I was looking for.
 
I use a 1.5 so it will mount up with my clip on but I have a prs stock on it so I can raise my cheek up to it. I liked it so much on my precision ar I did it with the others too. No regrets either. It's just a lot better to have that stock on it or one that you can adjust the comb on

I'll have to measure my mount. I measured from centerline of bore to centerline of scope body with a tape measure and got 2 5/8", or 2.625".

I have to scrunch my head down to get lined up, and doing ready up's it seems I should be faster. I'll have to look for a taller mount for a more relaxed head position. The mount I have now is just a cheap one I got from a buddy. No idea what brand.

Likely because you’re using a HOB measurement vs optical mount height instead. Most people don’t refer to LPVO height with HOB.

Lowest I will do with LPVO is a 1.7” optical height over the rail. I think 1.7-1.9 is the sweet spot for mount height on a LPVO and 1.9 on a red dot for me.

I measured my mount today. 1.375"

It is short compared to what you all have. No wonder I have to scrunch up lol.

Definitely gotta look for a bit taller mount. I appreciate all the responses.

Another random reference is most AR rail mounted iron sights are ~1.41" from the top of the Picatinny rail to the center of the rear aperture.
 
Why does it matter. Setup your gun for you and your comfort. They used to be lots of shenanigans about low height over bore.

And yet those iron sights are way up high.

If you are happy, it's all that matters

I ran the numbers on all of my AR pattern guns and they are between 2.6" ~ 2.8" above bore.

MDT did a test where they built a skyscraper mount to evaluate the effect on precision/accuracy. The simple answer is pick whatever scope height you're most comfortable with. Whether it's high or low won't really matter once you have it zeroed.
