The PKS-07 is a 7x magnification Russian scope. The scope features chevron distance markers as opposed to the crosshairs and mil-dots of the rifle scope.
The PKS-07 is the default scope on the SVD, SV-98, SKS, and QBU-88, and JNG-90 in Battlefield 3. Chevrons are included for calculating Projectile arc over range. The American equivalent is the Rifle Scope.
Like the PSO-1, a stadiametric rangefinder is printed on the lower-left quadrant, but it is not accurately scaled.
