1.93" is the desired height for VPVO, especially when combined with a night illuminator like a PEQ.
The Super Precision® 1.93" Scope Mount was developed specifically for scenarios such as shooting while wearing a gas mask and/or Night Vision equipment. 1.93" is also an optimal height for the optic to clear most common range finders, lasers or IR devices such as a PEQ15. Once upon a time, someone asked what was the minimun rise needed for a Schmidt & Bender 1-8x to see over a PEQ-15 and the answer came back at 1.93". Now, with the larger occular in the Vortex Razor 1-6x, the 1.93" height gives a nicer heads up look through the larger lens.
The Geissele 1.03" black mount is precision machined from a single piece of 7075-T6 high strength aluminum, which is nice, as the cuts are perfect, and no lapping is needed.
The black mount is Type 3 hard coat anodized. Utilizing Geissele’s update of the classic nut and bolt method, this mount will attach your optic to your weapon with 2,800 pounds of clamping force, and features 4 shear lugs for maximum rigidity and return to zero.
