Breaking Down the Features of Primary Arms SLx 4.5-27x56mm Tube Rifle Scope, First Focal Plane

Specifications

• Objective Lens Diameter: 56 mm which allows for increased light gathering, especially important in low-light conditions. This larger objective lens translates to a brighter and clearer image, enhancing target acquisition and identification.

• Magnification: 4.5-27x offers a versatile range, suitable for both medium and long-range shooting. The wide magnification range allows for flexibility in various shooting scenarios, from close-quarters target practice to engaging distant targets.

• Tube Diameter: 34 mm provides a robust platform for the internal components and allows for a wider range of adjustment. This larger tube diameter enhances the scope’s durability and allows for greater elevation and windage adjustments, crucial for long-range precision.

• Reticle Focal Plane: First Focal Plane (FFP), meaning the reticle scales with magnification, maintaining accurate holdovers at any zoom level. This FFP design ensures that the reticle’s subtensions remain consistent regardless of the magnification setting, making it easier to estimate range and apply accurate holdovers.

• Illumination Color: Red, offering a clear and visible aiming point in various lighting conditions. The red illumination provides a distinct aiming point that contrasts well against various backgrounds, enhancing target acquisition in low-light or high-contrast environments.

• Adjustment Click Value: 0.1 Mil Rad, allowing for precise and repeatable adjustments. This fine adjustment value enables shooters to make minute corrections, improving accuracy at longer distances.

• Adjustment Type: Mil Rad, a common and intuitive system for making adjustments. The Mil Rad system is favored by many long-range shooters due to its compatibility with rangefinding and ballistic calculations.

• W/E Travel at 100 Yds: 110/80 MOA, providing ample adjustment range for various shooting distances and conditions. This generous travel range ensures that the scope can be zeroed and adjusted for a wide range of distances and environmental factors.

• Weight: 32.6 oz This is important to note, the scope is hefty and may affect rifle balance.
