The Finnish Defence Forces (FDF) 8.6 TKIV 2000 rifles have custom made Zeiss 3-12x56 Diavari VM/V T* 30 mm telescopic sights with eye safe laser filters mounted. These sights are equipped with first focal plane "FinnDot" reticles (a regular mil-dot reticle with the addition of 400 m – 1200 m holdover (stadiametric) rangefinding brackets for 1 meter high or 0.5 meter wide targets at 400, 600, 800, 1000 and 1200 m). Reticle is illuminated. Tritium ampoule embedded in the elevation turret is for setting BDC on quick engagement battle mode only.
The reticle elevation has 0.25 mil (0.25 mrad) adjustment intervals (total elevation range = 18.6 mils), while the windage has 0.1 mil adjustment intervals. The 0.25 mrad elevation click steps make make longer reaching one-turn adjustment range possible.
The elevation turrets have 100 m – 1400 m Bullet Drop Compensation (BDC) knobs calibrated for the Lapua Lock Base B408 cartridges the FDF issues its 8.6 TKIV 2000 marksmen. FDF snipers are trained to compensate BDC induced errors that inevitably occur when the environmental and meteorological circumstances deviate from the circumstances the BDC was calibrated for. All vital screw slots on tyhe telescopic sight are designed to be operated with .338 Lapua Magnum cartridges instead of screwdrivers.
