The lateral adjustment modifies the parallax of the scope, enhancing the clarity of the reticle and reducing the apparent movement when firing at varying ranges.
Model #175081 - VX-Freedom 6-18x40 Riflescope with a Tri-MOA Reticle, CDS and a Matte finish
Designed, Machined and Assembled in the USA. 100% Waterproof, fogproof, shockproof, and backed by Leupold's legendary customer care
Leupold's Custom Dial System (CDS) gives you the ability to customize your turret (adjustment dial) to your exact ballistics and environmental conditions. Once your new custom dial is installed, simply range the target, turn the dial to that number, and aim dead on.
In Second Focal Plane (rear focal plane) scopes, the reticle stays the same size while the target grows and shrinks when you adjust the magnification. These reticles are ideal for lowlight hunting situations and in scopes that don't utilize hash marks for range estimation.
