Frequently Asked Questions

What are the key features of the Leupold Mark 4 ER/T 4.5-14x50mm FFP riflescope?

The Leupold Mark 4 ER/T 4.5-14x50mm FFP features a Front Focal Plane reticle, M5 0.1 MRAD turrets, a 30mm tube made of T6061 aluminum, and is sealed with Argon/Krypton gas for waterproofing. It also boasts Leupold's Xtended Twilight Lens System for enhanced low-light performance.

How does the Front Focal Plane (FFP) design benefit a riflescope user?

An FFP reticle's size changes proportionally with magnification. This means the subtension values (like MRAD) remain consistent relative to the target at any power setting, enabling accurate range estimation and holdovers across the entire magnification range of the scope.

What is the 'box test' and why is it important for scope setup?

The 'box test' is a procedure to verify a riflescope's turret tracking accuracy and repeatability. It involves shooting a group, adjusting turrets to move the impact point in a square pattern, and confirming the scope returns precisely to its original zero point, ensuring reliable adjustments.

What is the typical price range for the Leupold Mark 4 ER/T 4.5-14x50mm FFP scope?

The street price for the Leupold Mark 4 ER/T 4.5-14x50mm FFP model is approximately $1600. Base models in the Mark 4 series can be found for around $800, with higher-end configurations reaching the $1600 mark.
