Frequently Asked Questions

How do you zero the Discovery HD 4-20x50 FFP scope?

To zero the Discovery HD 4-20x50 FFP scope, first ensure the firearm is safely unloaded. Mount the rifle on a rest, fire a shot at 25 meters, and observe the impact. Adjust the elevation and windage turrets by pulling them up and rotating to match the impact point to the aim point, then fire a confirmation shot. Finally, set the zero stop by aligning the '0' on the turret with the reference indicator.

What are the key features of the Discovery HD 4-20x50 FFP scope?

The Discovery HD 4-20x50 FFP scope features a first focal plane (FFP) reticle, which scales with magnification for consistent holdovers. It boasts high-definition optics for exceptional clarity and sharpness, a 30mm main tube, and adjustable parallax and illumination. The turrets offer precise MOA adjustments and a zero stop function.

How does the Discovery HD 4-20x50 FFP perform at different distances?

The scope performs well at various distances. After zeroing at 25 meters, it maintained accuracy at 50 meters without adjustment. At 100 meters, an initial drop was observed, which was corrected by adjusting the elevation turret by 2 MOA, resulting in a tight group.

What is the purpose of the zero stop on the Discovery HD scope?

The zero stop on the Discovery HD scope allows you to set a hard limit for the elevation turret's downward travel. This means after adjusting for longer ranges, you can quickly and easily return the scope to your primary zero point (e.g., 25 meters) by feeling the stop, ensuring consistent aiming.
