That's total centerline height, with the 0.5" CASV riser.

Spec on the 30mm XTR Mediums is 0.5", which is to the base of the rings, so add 0.59" for the centerline, which gives you a centerline height of 1.09. Add on the CASV height for 1.59" total.

Spec on the 30mm HRTs is 1.075", which is to the centerline, so the CASV height is added to that for 1.575" total.

Clear as mud? It's a wonder anyone gets their AR optics mounted right the first time - I sure learned the hard way. That's why you see so much mounting gear cheap on the arfcom ee!
