Note: The XLR reticle images are shown as seen through the Viper HS LR 6-24x50 riflescope. The appearance of the XLR reticle in other models may have slight variations.
The Viper® XLR Reticle
Designed to maximize long distance shooting and ranging abilities, the Viper® XLR™ MOA reticle can be used to effectively determine ranges, holdovers, windage, and moving lead corrections. Ultra-precision laser etching on the glass reticle ensures that MOA specifications will be kept to the tightest tolerances possible. The fine center crosshair subtensions on the XLR MOA reticle were carefully chosen to provide the optimum balance between precision aiming and low light visibility.

MOA Subtensions
The XLR reticle is based on minute-of-angle (MOA) subtensions. MOA measurements are based on degrees and minutes: 360 degrees in a circle, 60 minutes in a degree for a total of 21,600 minutes. These angular measurements are used to estimate range and correct for bullet trajectory drop in riflescopes. 1 MOA will correspond to 1.05 inches at a 100 yard distance, 2.1 inches at 200 yards, 3.15 inches at 300 yards, and so on.
First Focal Plane Reticles
When used in a first focal plane riflescope, such as this Vortex Viper HS LR riflescope, the MOA subtensions of the XLR reticle are valid at all magnification levels. This means the shooter can use the magnification level most appropriate for the situation and still have effective holdover and windage reference marks.
This is extremely valuable in a high-stress situation because the shooter does not have to remember to set the scope to one particular magnification to get valid holdovers—an action necessary in the more common second focal plane reticles.
Estimating MOA
Although 1 MOA is very commonly corresponded to 1 inch at 100 yards, this is not quite correct 1 MOA at 100 yards equals 1.05 inches. Calling 1 MOA an inch per 100 yards may be acceptable at shorter distances, but it will cause a five percent error in ranging and holdover adjustments. This will result in missed shots at longer distances.
