Frequently asked questions

Does the ARD fit all 40mm scope objectives?

The MK4 ARD is engineered for standard 40mm objective lenses used on Leupold and compatible optics. Verify your scope's objective diameter before ordering—this device requires exactly 40mm to fit properly and function as intended.

Will the anti-reflect device affect my scope's performance?

No. The ARD reduces glint without impacting light transmission or image quality. It's a passive accessory that sits in front of the lens and doesn't interact with the optical path.
