Windage and Elevation Adjustment
Use a 1.5mm metric hex wrench to loosen the three set screws located along the scalloped edge of the elevation turret. Next, lock down the locking thumb screw on top of the knob. Then rotate the knob and set the MOA hash marks back to zero. Once the knob is zeroed, retighten the three set screws making sure not to over-torque and strip them. After all three set screws are sufficiently tightened, the mechanism will re-engage.
MD Reticle
The US Army Mil Dot reticle (MD and MDD) comes in two illumination versions. The MD reticle, initially Sightmark’s standard reticle, illuminates the entire Mil-Dot crosshair. This is intended to provide the shooter a keen aiming point for assistance in accurate shooting. In order to use the Mil-Dot reticle accurately, please read the following: Mil stands for millradian, 1/1623.2th of a circle or 3.438 MOA. The millradian represents 1 unit at 1000 yds. To simplify, a target that is one yard tall at 1000 yds would measure 1 millradian.
Parallax Adjustment
Sightmark’s higher magnification riflescopes do come equipped with a parallax adjustment knob. Parallax is the change of angular position of two stationary points relative to each other as seen by an observer. In other words, it’s how the image lines up in the riflescope and how the eye perceives it. Be sure to adjust the parallax knob to the correct shooting range. It is very important to keep this in mind when zeroing the rifle. If this is not taken into consideration at the time of sighting in the riflescope, accuracy will diminish.
