What's the height of the sight over bore offset with the ACR, using normal AR sights? I know the SCAR is taller than a normal AR; is the ACR?

I believe the hight-over-bore is the same as the AR.

That seems odd; there's a visible difference between the rail/bore distance on my ACR and my AR. Perhaps a quarter inch? At any rate, I'm pretty sure it's not the same as an AR; does anyone have an actual measurement? Bushmaster didn't seem to understand what I wanted or why.

Mine is coming tomorrow so I can't confirm how acurate this is but I found these figures: AR15= 1.5" ACR=1.75"
