Components Overview

Familiarize yourself with the main components of your LH-4 FFP Rifle Scope:

Setup

Mounting the Scope

The LH-4 FFP Rifle Scope features a 30mm main tube, compatible with various mounting systems including Integral Mount, Dovetail Mount, Weaver Mount, Cantilever Mount, or Picatinny Mount. Ensure your chosen rings and mount are appropriate for a 30mm tube and are securely fastened to your firearm. Proper mounting is crucial for maintaining zero and accuracy.

Zeroing the Turrets

The LH-4 features fully capped, tool-less turrets for both windage and elevation adjustments. After initial bore sighting, make precise adjustments at the range. The turrets provide tactile clicks for precise changes. Once zeroed, the caps can be replaced to protect the turrets from accidental adjustments and environmental elements.

Parallax Adjustment

The scope includes an adjustable parallax knob, typically located on the side of the main tube. Rotate this knob to achieve a clear, sharp image of your target and reticle at various distances. Adjust until the reticle appears stationary relative to the target when you move your head slightly.

Illumination Control

The illuminated reticle feature enhances visibility in low-light conditions. The illumination control is integrated with the parallax knob. Rotate the outer ring of the parallax knob to adjust the brightness of the reticle to suit ambient light conditions.

Operating the Scope

Magnification Adjustment

The LH-4 FFP Rifle Scope offers a variable magnification range (e.g., 4-16x44 or 6-24x50, depending on the specific model). Rotate the magnification ring located near the eyepiece to adjust the power. As a First Focal Plane (FFP) scope, the reticle size will change proportionally with the magnification, allowing for accurate holdovers at any power setting.

Reticle Usage

The VHR-MIL (or VHR-MOA) reticle is a Christmas tree style design, providing multiple aiming points for bullet drop compensation and windage corrections. Utilize the hash marks and dots on the reticle to estimate distances and make precise adjustments without altering the turrets. Practice with your specific ammunition and rifle to understand the reticle's subtensions at various ranges.

Maintenance

Proper maintenance ensures the longevity and performance of your Arken Optics LH-4 scope.

• Cleaning Lenses: Use a soft brush to remove loose dust and debris. For smudges or fingerprints, use a lens cleaning cloth and a small amount of lens cleaning solution. Avoid using harsh chemicals or abrasive materials.
• Cleaning Exterior: Wipe the exterior surfaces with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, followed by a clean, damp cloth to remove any residue.
• Storage: Store the scope in a cool, dry place, away from direct sunlight and extreme temperatures. Use lens caps to protect the objective and ocular lenses when not in use.
