Setup and Installation
Mounting the Scope:
- Ensure your firearm is unloaded and safe.
- Attach the integrated cantilever mount to your rifle's Picatinny or Weaver rail. Ensure the mount is securely fastened using the provided screws.
- Position the scope on the mount, ensuring proper eye relief for your shooting stance.
- Tighten the scope rings evenly to secure the scope without over-tightening. Use a torque wrench if available to prevent damage.
- Note: Applying a small amount of Loctite to the mounting screws is recommended to prevent loosening from recoil, as suggested by user reviews.

Operating Instructions
Adjusting Magnification:
Rotate the magnification ring located near the eyepiece to adjust between 1x and 4x magnification. This allows for quick target acquisition at 1x and precise aiming at higher magnifications.
Windage and Elevation Adjustments:
The scope features external locking windage and elevation turrets. To make adjustments, pull up on the turret knob to unlock it, make your 1/2 MOA click adjustments, and then push the knob down to lock it in place. This prevents accidental changes to your zero.

Illuminated Reticle:
The mil-dot reticle can be illuminated in red or green. Use the adjustable rheostat dial on the side of the scope to select the desired color and brightness level. This feature is particularly useful in low-light conditions or against dark backgrounds.

Maintenance
- Lens Cleaning: Use the included lens cloth or a soft, lint-free cloth to gently wipe the objective and ocular lenses. For stubborn smudges, use a lens cleaning solution specifically designed for optics. Avoid using abrasive materials or harsh chemicals.
- Body Cleaning: Wipe the scope body with a damp cloth to remove dirt and debris. Ensure all external surfaces are dry before storage.
- Storage: Store the scope in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided flip-up caps to protect the lenses when not in use.
- Waterproof/Fogproof: While the scope is designed to be waterproof and fogproof, avoid prolonged submersion or exposure to extreme conditions beyond its design limits.
The accessories included with the scope: a coin for battery compartment, flip-up lens caps, and a cleaning cloth, essential for maintenance.
