The FFPS3940-R comes equipped with an adjustable 3-9x magnification for targeting out to 600 yards and beyond. The functionally designed first focal plane range finder reticle allows for faster range estimation and holdover correction.

The responsive touch-button reticle illumination switch allows rapid reticle illumination adjustment with minimal movement. The FFPS3940-R has 1/4 MOA/click windage and adjustment knobs with resettable zeroes and turret locks to prevent slippage.
