SIGHT ADJUSTMENTS AND ZEROING
C79 OPTICAL SIGHT
The C79 optical sight has both azimuth and elevation adjustments. Range adjustments are from 200 to 800 metres
in 100 m increments.
NOTE
Zeroing is normally carried out at 100 m.
* Set the range dial to 200 m.
* Fire a five round group, maintaining the same Point of Aim (POA).
* Identify the Mean Point of Impact (MPI) and adjust the azimuth and elevation to bring the POA on to the MPI.
* To adjust azimuth, insert a coin into the azimuth shaft slot and rotate clockwise or counter clockwise. Rotating
the azimuth shaft clockwise moves the MPI right (1 click moves the MPI 2.5 cm or 0.25 mil at 100 m).
* To adjust elevation, disengage the elevation dial lock by inserting a coin into the lock groove and moving the
lock up. Rotate the range dial clockwise or counterclockwise. Rotating the range dial clockwise with the lock
disengaged will move the MPI down (1 clock moves the MPI 2.5 cm or 0.25 mil 100 m).
* When the MPI and POA coincide, rotate the range dial counterclockwise two clicks on a C7 or LSW (three clicks
on a C8 or SFW) and engage the lock. This will ensure that the sight is zeroed at all ranges.
REAR SIGHT, DETACHABLE IRON SIGHT, OR BACK-UUP SIGHT
Non-optically sighted C7 Family weapons and weapons fitted with the DIS or the back-up sight utilize a common
two aperture flip sight. The large aperture (battle sight) is used for short range or low light conditions. The small
aperture can be used at all ranges. To adjust windage: depress the windage drum detent with the point of a
bullet and rotate the windage drum clockwise or counterclockwise. To move the MPI right, rotate the drum
clockwise as indicated by the arrow.
* One notch of rotation moves the MPI 2.8 cm or 0.28 mil at 100 m for the Rifle and LSW.
* One notch of rotation moves the MPI 3.8 cm or 0.38 mil at 100 m for the Carbine and SFW.
