Second Focal Plane Rifle Scopes

Second Focal Plane

Second focal plane (SFP) scopes place the reticle behind magnification lenses. This feature means that the reticle size stays the same, no matter the magnification leve.

Hunters and shooters who want a steady aiming point prefer this design. It keeps the reticle easy to see at all ranges. Some shooters don’t appreciate that the hash marks on the reticle only show accurate measurements at full magnification. These marks indicate holdover values—for instance, a scope with a 3.6-18x range. The hash marks represent 1 MOA only at 18x. At lower magnifications, their values shift, which requires some mental math for precise shooting.

Despite this complexity, SFP scopes are popular because they offer consistent reticle visibility. It makes them a good choice for different shooting situations. They also work well with ballistic turrets. You can make precise adjustments without constantly recalibrating the reticle, and some shooters won’t use any other scope since SFPs are so reliable. Overall, SFP scopes are easy to use. That’s why many hunters and recreational shooters prefer them. They’re a solid choice for those who value consistency in their optics.
