The zero range, , is important because corrections due to elevation differences will be expressed in terms of changes to the horizontal zero range. For most rifles, is quite small. For example, the standard 7.62 mm (0.308 in) NATO bullet is fired with a muzzle velocity of 853 m/s (2800 ft/s).
In contrast to most other eye glasses, shooting glasses usually only have one lens that corrects the ametropia of the dominant eye, which is used for aiming.This lens is selected in such a way that the maximum visual acuity lies on the font sight line element near the muzzle of the (non-magnifying) open type or diopter and globe type match sight line elements to get three points positioned in ...
Any errors in range estimation are effectively irrelevant, as a well-aimed shot will hit the torso of the enemy soldier. No height correction is needed at the "battle zero" or less distance, but it can result in a headshot or even a complete miss. The belt buckle is used as battle zero point of aim in Russian and former Soviet military doctrine.

Boresighting is a method of visually pre-aligning a firearm barrel's bore axis with the target, in order to more easily zero the gunsight (optical or iron sights). The process is usually performed on a rifle, and can be accomplished either with the naked eye, or with a specialized device called a boresighter. [1]
Because when using a telescopic sight, the crosshair lines geometrically resemble the X- and Y-axis of the Cartesian coordinate system where the reticle center is analogous to the origin point (i.e. coordinate [0,0]), the designated sighting-in point is known as a zero, and the act of sighting-in is therefore also called zeroing.
With tangent sights, the rear sight is often used to adjust the elevation, and the front the windage. The M16A2 later M16 series rifles have a dial adjustable range calibrated rear sight, and use an elevation adjustable front sight to "zero" the rifle at a given range. The rear sight is used for windage adjustment and to change the zero range.
