Safety Information

Always handle firearms and optical equipment with extreme care. Adhere to all local and national firearm safety regulations. Never look directly at the sun or any intense light source through the scope, as this can cause permanent eye damage.

  • Ensure the firearm is unloaded and safe before mounting or adjusting the scope.
  • Always point the firearm in a safe direction.
  • Keep your finger off the trigger until ready to shoot.
  • Be sure of your target and what is beyond it.
  • Store the scope and firearm securely, out of reach of children.

Components Overview

The ESSLNB 3-9X50mm Rifle Scope is designed for durability and precision. Key components include:

  • Objective Lens: The front lens, 50mm in diameter, gathers light for a bright image.
  • Eyepiece: The rear lens through which you view the target.
  • Magnification Ring: Adjusts the zoom level from 3x to 9x.
  • Windage and Elevation Turrets: Used for adjusting the point of impact.
  • Illumination Control: Adjusts the brightness and color of the reticle.
  • Sunshade Tube: Attachable tube to reduce glare from direct sunlight.

Setup

Mounting the Scope

The ESSLNB rifle scope comes with 20mm/22mm Picatinny/Weaver rail mount rings for secure attachment to your firearm.

  1. Attach Mount Rings: Secure the provided ring mounts to your firearm's Picatinny or Weaver rail. Ensure they are spaced appropriately to support the scope evenly.
  2. Position the Scope: Place the rifle scope into the lower halves of the mount rings. Adjust the scope's position forward or backward to achieve proper eye relief. Eye relief is the distance between your eye and the eyepiece that provides a full, clear field of view.
  3. Level the Reticle: Rotate the scope within the rings until the reticle is perfectly level. This is crucial for accurate shooting.
  4. Secure the Rings: Attach the upper halves of the mount rings and tighten the screws evenly. Do not overtighten, as this can damage the scope tube.

Battery Installation (for Reticle Illumination)

The reticle illumination requires one CR2032 battery (not included in some packages). The battery compartment is typically located on the illumination control knob.

  1. Locate the battery cap on the illumination control knob.
  2. Unscrew the cap counter-clockwise.
  3. Insert one CR2032 battery with the positive (+) side facing outwards.
  4. Screw the cap back on clockwise until snug. Do not overtighten.

Operation

Adjusting Magnification

The scope features a variable 3-9X magnification. To adjust, simply rotate the magnification ring located near the eyepiece. Turn it clockwise to increase magnification and counter-clockwise to decrease it.

Reticle Illumination

The scope offers red, green, and blue reticle illumination with three brightness levels for each color. This feature enhances visibility in various lighting conditions.

  • Rotate the illumination control knob to select the desired color (Red, Green, or Blue).
  • Continue rotating the knob to cycle through the three brightness levels for the selected color.
  • Turn the knob to the "OFF" position when illumination is not needed to conserve battery life.

Focusing and Parallax Adjustment

Adjust the eyepiece to achieve a sharp reticle image. For parallax, if your scope has an adjustable objective (AO) or side focus knob, rotate it until the target appears clear and the reticle does not shift relative to the target when you move your head slightly.

Zeroing the Scope (Windage and Elevation)

Zeroing is the process of aligning the scope's point of aim with the firearm's point of impact at a specific distance.

  1. Preparation: Set up a target at your desired zeroing distance (e.g., 50 or 100 yards). Ensure your firearm is securely rested.
  2. Initial Shots: Fire a group of 3-5 shots. Observe where the shots impact relative to your aim point.
  3. Adjust Elevation: If shots are high, turn the elevation turret (top) clockwise to move the point of impact down. If shots are low, turn it counter-clockwise to move the point of impact up.
  4. Adjust Windage: If shots are right, turn the windage turret (side) clockwise to move the point of impact left. If shots are left, turn it counter-clockwise to move the point of impact right.
  5. Fine-tuning: Make small adjustments and fire additional groups until your shots consistently hit the center of the target.

The scope features Mil-Dot reticles which can be used for estimating distances to targets once you are familiar with their subtensions.

Maintenance

Cleaning the Lenses

To maintain optical clarity, keep the lenses clean. Use the provided cleaning cloth or a soft, lint-free cloth designed for optics. For stubborn smudges, use a small amount of lens cleaning fluid.

  • Gently brush off any loose dust or debris from the lens surface.
  • Apply a small amount of lens cleaning fluid to the cloth, not directly to the lens.
  • Wipe the lens in a circular motion from the center outwards.
  • Avoid touching the lens surfaces with your fingers.

General Care and Storage

The scope is constructed from durable aluminum alloy and is designed to be waterproof, fog-proof, and shock-proof. However, proper care will extend its lifespan.

  • Always use the lens covers when the scope is not in use to protect the lenses from scratches and dust.
  • Store the scope in a cool, dry place, away from direct sunlight and extreme temperatures.
  • Avoid dropping or subjecting the scope to severe impacts.
  • If the sunshade tube is used, ensure it is securely attached to prevent glare.
