    A milliradian (SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). ). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or

    Perhaps the most popular and well-known ranging reticle is the mil-dot reticle, which consists of a duplex crosshair with small dots marking each milliradian (or "mil") intervals from the center. [23] An alternative variant uses perpendicular hash lines instead of dots, and is known as the mil-hash reticle.

    Mil-dot reticle as used in telescopic sights. • If the helmeted head of a man (≈ 0.25 m tall) fits between the fourth bar and the horizontal line, the man is at approximately 100 meters distance. • When the upper part of the body of a man (≈ 1 m tall) fits under the first line, he stands at approximately 400 meters distance.

    en.wikipedia.org/wiki/Reflector_sight

    Sights that use dot reticles are almost invariably measured in minutes of arc, sometimes called "minutes of angle" or "moa". Moa is a convenient measure for shooters using Imperial or US customary units , since 1 moa subtends approximately 1 in (25 mm) at a distance of 100 yd (91 m), which makes moa a convenient unit to use in ballistics ...

    These sights are equipped with first focal plane "FinnDot" reticles (a regular mil-dot reticle with the addition of 400 m – 1200 m holdover (stadiametric) rangefinding brackets for 1 meter high or 0.5 meter wide targets at 400, 600, 800, 1000 and 1200 m). Reticle is illuminated.

  9. Sniper - Wikipedia

    en.wikipedia.org/wiki/Sniper

    To determine the range to a target without a laser rangefinder, the sniper may use the mil dot reticle on a scope to accurately find the range. Mil dots are used like a slide rule to measure the height of a target, and if the height is known, the range can be as well. The height of the target (in yards) ×1000, divided by the height of the ...
