This will also have the effect of magnifying the sight so the red dot or holographic reticle will appear larger as well. When flipped in, the user will also have to account for parallax and eye relief. The non-magnified optic and the magnifier is placed so that the user will have the correct amount of eye relief when looking through the ...
Optics showing eye relief and exit pupil 1 Real image 2 Field diaphragm 3 Eye relief 4 Exit pupil. Eye relief distance can be particularly important for eyeglass wearers and shooters. The eye of an eyeglass wearer is typically further from the eyepiece, so that user needs a longer eye relief in order to still see the entire field of view.
After reviewing feedback from the soldiers who used the sight, Elcan produced the fourth generation mount C79, known as the C79A2, and is mounted onto the C7A2 rifle, as well as the C8A3 carbines. The C79A2 sight is a component of the C7A2 mid-life update program of the Canadian Forces' inventory of C7A1 rifle systems.
The longer the focal length of the eyepiece, the greater the eye relief. Typical telescopic sights may have eye relief ranging from 25 mm (0.98 in) to over 100 mm (3.9 in), but telescopic sights intended for scout rifles or handguns need much longer eye relief to present a
The optimum eye relief distance also varies with application. For example, a rifle scope needs a very long eye relief to prevent recoil from causing it to strike the observer. [1] The exit pupil can be visualized by focusing the instrument on a bright, nondescript field, and holding a white card up to the eyepiece.
Since dot sights can be mounted at any distance from the shooter's eye with no issues of focus, military rifle mounts usually place the sight in any mechanically-convenient mounting position, such as the carrying handle of the M16 rifle, or on a rail system, typically a Picatinny rail, on top of the rifle. This leaves plenty of room for night ...

The optic is fitted to the rifle with A.R.M.S. locking levers to a normal Picatinny rail (MIL-STD 1913 rail) 70 mm (2.8 in) from the shooter eye. The optic is zeroed at 100 m (109 yd) range the azimuth/windage is adjusted in ½ MOA increments by flathead screwdriver on the front right of the optic and the elevation is adjusted in ½ MOA ...
