Leupold FX-I Rimfire 4x28 Fine Duplex rifle scope

The Leupold FX-I Rimfire 4x28 1" Fine Duplex is an uncomplicated optical sight designed specifically for side-firing weapons. It stands out for its sharp and brilliant image quality, waterproof construction, and precise Duplex reticle with 0.25 MOA adjustment.

Part of the budget-friendly Golden Ring series, the Leupold FX-I Rimfire 4x28 1" Fine Duplex is a classic optical sight that offers excellent value for its price.

Construction-wise, the sight features a one-piece (inch) tube made of anodized aircraft-grade aluminum. This construction ensures durability against shock, recoil, corrosion, and scratches.

To prevent internal lens evaporation, the scope is filled with dry nitrogen gas, making it reliable even in challenging conditions. Its fully waterproof design allows for use in rainy, foggy, or other humid environments without any concerns.

The optical system incorporates Multi-coat 4 lenses, delivering a bright and clear image with exceptional contrast and edge-to-edge field of view clarity, even in low light situations.

The scope comes with a factory-set parallax of approximately 54 meters, optimized for the typical shooting distances encountered with side-firing weapons.

For precision shooting at small targets, the scope utilizes a Fine Duplex sighting reticle, featuring a hair-thin crosshair that is finer than the standard Duplex reticle.

The turrets are low-profile and offer 1/4 MOA adjustments. The crosshair can be adjusted vertically and horizontally within a range of 80 MOA. The turrets have moled walls, enabling easy adjustment without the need for additional tools.
