Here you can see the direct height comparisons for the Absolute, Lower 1/3 and 1.93 Super Precision T1 Mounts. The 1.93 will allow you get up over a PEQ.
Made from 7075 aluminum, they are available in Black or DDC (Desert Dirt Color) type 3 hard coat anodize.

I’ve seen the 1.93″ mounts from multiple companies now. I’m simply curious, does anyone know why the 1.93″ specifically was chosen? For instance, why not a 1.90″ or 2.0″? I understand the desire for a mount in this height range, but am just curious how/why 1.93″ specifically has become the standard.
Thank you
1.93″ is made so that the optic clears a PEQ-15. More important for variable optics like the Vortex Razor than reddots, though.
I could be wrong but I believe if you measure from the center of the bore to the center of your optic with a 1.93″ mount it puts your dot at 2″ above center bore on an AR platform.
Actually- it might be more like 2.5″. But I think measuring from center bore is where you’ll achieve the nice round number.
Thanks guys,
I understand the result of having an unobstructed field of view over a PEQ.
But specifically I am curious why the number 1.93″ was chosen over something such as 1.8, 1.9, or 2.0.
1.93″ just seems to be a very specific number. I am assuming that it was chosen intentionally. I just wonder why someone along the way chose 1.93 instead of something else. I know Larue has done a 1.93 for some time now. Just never heard who the first person was to develop that number.
Simply curious is all.
It basically was empirically tested by some high speed, low drag guy. Mark Larue kept sending him different heights of mounts based on his feedback and 1.93″ turned out to be about perfect.
Here’s where I heard that from if you want the full story. About 8:30 mark.

You really should check out Primary & Secondary on Youtube if you haven’t already. A lot of great info out there.
Thank you Vic, that is very helpful
+1 very interesting podcast.
What does the other side look like? I’m guessing these aren’t QD.
It’s a 1/2″ nut which takes a wrench, but it does have a flat head slot milled into it.
