3-12×42 V2 M-RG Tactical AO Scope – Open Box

The Monstrum Tactical S31242-M-RGAO-V2 is a full-featured scope ready for hunting, target practice, or tactical use with a Mil-dot reticle. Crystal clear optics with an impressive 3-12x magnification. This scope has a functionally designed Mil-dot reticle for faster range estimation and holdover correction. The etched black reticle is always visible without illumination or can be lit red or green for better reticle visibility at night or low light environments. The adjustable objective (AO) lens can be moved by the side parallax dial. This setting allows for a sharper target image, elimination of parallax, and range estimation. This scope has 1/4 MOA/click windage and elevation adjustment dials with locking turrets.

What is Parrallax?

In terms of shooting, parallax refers to the alignment of the shooter’s eye in relation to the scope reticle and the target object. Unless properly focused, a shift in eye position will result in a shift in the position of the reticle relative to the target – the parallax effect. With a fixed objective lens scope (without AO), small shifts in eye position may result in imprecise targeting and less accurate shooting.
