Riflescope Buyer's Guide: First Focal Plane vs. Second Focal Plane

Most riflescopes designed for hunting feature second focal plane reticles – meaning the reticle is etched on a static lens such that it does not change in scale at any magnification. The marks on a second focal plane reticle are typically calibrated for the highest magnification on a variable power scope (ex. on a 5-25 power riflescope, the reticle would be calibrated for 25 power). This means that at half-power (15 power on a 5-25 scope) the reticle measurements will be twice what they are at full power. For example, if each mark is measured in .25 MOA increments, the same marks at half-power will be .5 MOA. On the contrary, first focal plane reticles increase in scale as the magnification is increased. As a result, the reticle marks represent the same measurements at any magnification. A .25 MOA reticle marker is a true .25 MOA at 5 power, 6 power, 7 power, and so on. For more information on riflescopes visit: https://outdoorsmans.com/scopes
