Instructions
Zero in your Simmons scope using the recticle adjustment dials on the top and the right side of the scope. Rotate the top dial clockwise to bring the reticles down and counter-clockwise to move them up. Rotate the right side dial clockwise to move the reticles left and counter-clockwise to move them right.
Set the scope magnification settings as desired by turning the variable power ring (located on the eyepiece) to the appropriate magnification.
Adjust the parallax adjustment dial located on the left side of the scope (on certain models) to the range of the target. Parallax error is the optical illusion of target movement caused by shifts in the shooter's line of sight, which is more pronounced at longer ranges.
