3. Setup
3.1 Mounting the Riflescope
The Simmons 4-12x40 8 Point Riflescope comes with extra-high Weaver mounting rings. Ensure your rifle has a compatible Weaver-style base.
- Secure the Rings: Attach the Weaver mounting rings to your rifle's base, ensuring they are spaced appropriately for the riflescope's length and your preferred eye relief. Tighten the base screws securely.
- Position the Riflescope: Place the riflescope into the bottom halves of the rings. Do not tighten the top halves yet.
- Adjust Eye Relief: With the rifle shouldered in your natural shooting position, slide the riflescope forward or backward in the rings until you achieve a full, clear field of view without any dark crescent shadows (vignetting). The eye relief for this model is approximately 3.5 inches.
- Level the Reticle: Rotate the riflescope within the rings until the reticle is perfectly level with the rifle.
- Tighten Rings: Once eye relief and reticle level are set, carefully tighten the top halves of the mounting rings evenly, alternating between screws to ensure even pressure. Do not overtighten.
3.2 Initial Adjustments
- Focus the Eyepiece: Point the riflescope at a clear, bright area (like the sky) and quickly glance through the eyepiece. If the reticle is not sharp, rotate the eyepiece until it appears crisp. Avoid staring through the scope while adjusting.
- Zeroing: After mounting, the riflescope must be zeroed to your rifle and ammunition at a specific distance. This involves firing shots at a target and adjusting the windage and elevation turrets until the point of impact matches your point of aim. Refer to standard zeroing procedures for your specific firearm.
4. Operation
4.1 Magnification Adjustment
The riflescope features a 4-12x magnification range. To adjust the magnification, rotate the ring located near the eyepiece. Turn it clockwise to increase magnification and counter-clockwise to decrease it. Select the appropriate magnification based on your target distance and desired field of view.
4.2 Windage and Elevation Adjustments
The riflescope is equipped with 1/4-MOA SureGrip audible-click windage and elevation adjustments, featuring the TrueZero system.
- Elevation Turret: Located on top of the main tube. Turning it adjusts the vertical point of impact. Typically, turning clockwise moves the point of impact down, and counter-clockwise moves it up. Each click represents 1/4 Minute of Angle (MOA) at 100 yards.
- Windage Turret: Located on the right side of the main tube. Turning it adjusts the horizontal point of impact. Typically, turning clockwise moves the point of impact right, and counter-clockwise moves it left. Each click represents 1/4 MOA at 100 yards.
- TrueZero System: This system is designed to ensure that once zeroed, your adjustments remain locked, maintaining accuracy even under recoil or movement.
4.3 Quick Target Acquisition (QTA) Eyepiece
The QTA eyepiece is designed for fast and easy target acquisition. Once the eyepiece is properly focused for your eye, it allows for rapid target identification and aiming.
5. Maintenance
5.1 Cleaning
- Lenses: Use a soft lens brush or compressed air to remove dust and loose debris. For smudges or fingerprints, use a clean microfiber lens cloth and a small amount of lens cleaning fluid. Wipe gently in a circular motion. Avoid using harsh chemicals or abrasive materials.
- Body: Wipe the riflescope body with a soft, damp cloth to remove dirt or grime. Ensure all external surfaces are dry before storage.
5.2 Storage
Store the riflescope in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, consider using a protective case or cover to prevent dust accumulation and accidental damage.
