Second Focal Plane Reticles

This PST riflescope model uses a second focal plane (SFP) reticle. The

advantage of a SFP reticle is that it always maintains the same appearance.

Shooters using reticle hashmarks should be aware that the listed

subtensions used for estimating range, holdover, and wind drift correction

are only accurate at the 4x magnification.
