For example, with a typical Leupold brand 16 minute of angle (MOA) duplex reticle (similar to image B) on a fixed-power telescopic sight, the distance from post to post, between the heavier lines of the reticle spanning the center of the sight picture, is approximately 32 inches (810 millimeters) at 200 yards (180 m), or, equivalently ...

The mount is found on the left side of the rifle receiver, with machined cutouts for reduced weight and ease of installation; an example is the PSO-1 optical sight. Similar rails can also be found on rifles such as the Dragunov sniper rifle (SVD), the PSL rifle , the PKM as well as some AK series assault rifles from 1954 onwards.

[2] Holographic sights therefore have the ...
