FAQ

❓What distance is a 1-6x LPVO best suited for?

A 1-6x LPVO is designed for flexible use across short to intermediate distances. The 1x setting provides a wide view for close-range use, while higher magnification helps with target identification and more precise aiming at greater distances.

❓When should I use 1x and when should I use 6x?

Use lower magnification when a wider field of view and faster target acquisition are important. Increase the magnification when the target is smaller, farther away, or requires more precise aiming.

❓Why does the eye box feel tighter at higher magnification?

As magnification increases, the exit pupil becomes smaller and eye positioning generally becomes more critical. Keeping a consistent head position behind the scope helps maintain a full, clear sight picture.

❓Should I zero an LPVO at 1x or 6x?

Higher magnification generally makes it easier to see the aiming point and evaluate shot placement during zeroing. Once zeroed, the point of impact can be verified at other magnification settings.
