The riflescope features capped reset turrets for precise adjustments. Each click of the turret represents 1/4 MOA (Minute of Angle) of adjustment. To make adjustments:
- Remove the turret cap.
- Pull up the turret knob to disengage the locking mechanism.
- Rotate the knob to make the desired adjustments. The clicks are tactile and audible for precise control.
- Once adjustments are made, push the turret knob down to lock it in place.
- To re-index the turret to zero after sighting in, pull up the turret knob, rotate it until the '0' aligns with the indicator mark, and then push it back down.

Dead-Hold BDC (MOA) Reticle
The Dead-Hold BDC (MOA) reticle is a Second Focal Plane (SFP) reticle. This means the reticle's size appears constant regardless of the magnification setting. The hashmarks on the reticle provide quick reference points for bullet drop compensation (BDC) and windage corrections at various distances.
To effectively use the BDC reticle, it is recommended to:
- Familiarize yourself with your specific ammunition's ballistic data.
- Practice at various ranges to understand the holdover points for your setup.
- Use the provided reticle manual (if applicable) or online ballistic calculators from Vortex to determine precise holdover values for different distances and environmental conditions.
