The reticle of the Optical Sight provides the shooter with easily located aiming marks to designate the 
target at both short and long ranges. 

  

3.6.1

 

The main horizontal line is intended to provide a reference to the  marksman. This main horizontal 

line also coincides with the 100 meter aiming point. This reticle pattern is designed to be zeroed at 100 
meters. 
  

3.6.2

 

A central aiming feature (either a fine cross or a chevron) is placed at the reticle centre.  This 

aiming point is designed for use during for direct fire at 200 meters or closer. 
  

3.6.3

 

The ballistic reticle also provides aiming marks for various extended ranges.  Most ranges are 

labelled beside the aiming mark.  To assist in sight picture clarity, a 200m aiming mark has been omitted. 
At each range, the width of the horizontal aiming mark represents 19” on  the target.
