Frequently Asked Questions

What are the key features of the Discovery Optics ED-PRS 4-20x52 Gen 2 scope?

The ED-PRS 4-20x52 Gen 2 features user-resettable turrets with .1 MRAD clicks and a zero stop, a parallax knob with a unique raised design to prevent accidental adjustments, and a red illuminated reticle with six intensity levels. It also includes a 3-inch sunshade and a screw-on throw lever.

How does the Discovery Optics ED-PRS 4-20x52 compare to the 5-25x52 model?

The 4-20x52 is slightly shorter and lighter than the 5-25x52, making it more compact. The reviewer suggests that for many users, the practical performance is similar, as high-magnification scopes are often dialed down from their maximum power for better image quality.

What is the optical performance like on the ED-PRS 4-20x52 scope?

The scope offers good optical clarity and sharpness, especially at lower magnifications. At 20x, it provides good detail, though some minor chromatic aberration may be visible against high-contrast backgrounds, which is often more apparent in camera recordings than to the naked eye.

Does the Discovery Optics ED-PRS 4-20x52 scope track accurately?

Yes, the scope's turret tracking was tested and confirmed to be accurate. It passed a 'box test' and demonstrated reliable return to zero after making adjustments, indicating good mechanical integrity for dialing in shots.
